It is the maincenter unit of starter-generator.The function of controller, which is realized, to be needed by each of sensing module detection starter-generator operation
Type state parameter, corresponding regulation operation is performed on the basis of state parameter.
The structure of main motor, both at salient-pole structure, can lead to as shown in figure 3, including having stator 101 and rotor 102
Cross the salient pole that silicon steel plate stacking forms stator and rotor.The non-permanent magnet material of rotor 102 makes, and without winding.Stator
101 include polyphase windings, and each of which phase winding is by a pair of winding coil strings on the salient pole diametrically of stator 101
Connection or composition in parallel.The number of phases that stator 101 includes can at most reduce torque pulsation, but the number of phases can also make circuit structure more
It is increasingly complex and increase in power inverter opening and device.Therefore, as shown in figure 3, stator 101 is using the pole of six phase 12/10
Structure, the pole structure of six phase 12/10 can support two-phase/three-phase mixes to start, be increased using start mode more than two-phase and two-phase
Load capacity in big starter-generator starting process, thus there is more preferable starting performance.
Main motor can be found in Fig. 4 in the operation principle of starting process and be explained.For simplicity, Fig. 4 with stator 101 its
In exemplified by a phase winding, show the phase winding and corresponding power converter circuit structure.When the footpath of the B phase windings in Fig. 4
When being overlapped to axis with rotor pole axis, first switch S1 and second switch S2 is closed, stator A phase windings is powered, so as to by A
Phase winding provides magnetic flux.The magnetic line of force of A phase windings generation is along A phases stator poles-air gap-rotor pole-iron core-rotor pole-air gap-
The direction extension of A phase stator poles forms loop.Because now the longitudinal axis of A phase windings and the axis of rotor pole are misaligned, turn
Son so transports the longitudinal axis of rotor pole towards A phase windings by by the pulling force torque of the magnetic line of force bent in air gap
It is dynamic.When rotor pole axis, which is gone to, to be overlapped with the longitudinal axis of A phase windings, stop the power supply to A phase windings, then to C phases around
Group power supply, continue to drive the longitudinal axis of rotor pole towards C phase windings to rotate, until the longitudinal axis of rotor pole and C phase windings
During coincidence, extremely power switching is provided to magnetic flux by B phase windings.So with each stator winding of A-B-C-B-A sequential control
Power supply and cut-out, so as to keep rotor continuously to run.
In power generation process, the rotor for the torque actuated main motor that engine provides, with the change of rotor-position, each phase
The inductance of winding also changes therewith；When the longitudinal axis of a phase winding overlaps with the axis of rotor, the inductance of the phase winding
For minimum value, when the longitudinal axis of winding and the axis of rotor are in 45 degree of angles, the inductance of the phase winding reaches maximum.Can
See, as rotor-position changes, the inductance of a phase winding is among raising and lowering alternating change.When the inductance of a phase winding
During in the decline stage, negative torque will be produced, is now in generating state, it is defeated that the mechanical energy for overcoming negative torque is converted into electric energy
Go out.Now control the switch connection phase winding of power inverter, make the phase winding output current phase, so as to starting-generating
The battery system feeding electric energy of machine connection.Therefore, it is necessary to switch connection and disconnection to power inverter in power generation process
Stage be controlled, ensure the switch connection stage generally in winding inductance decline during in.
It can be seen that each phase winding according to stator whether is required for relative to rotor in starting process or power generation process
The angle of axis, control being switched on and off for phase winding switch corresponding in power inverter.It will be described below, by
Controller detects the angle of rotor axis by sensing mould, and when the angle reaches corresponding turn-on angle, controller is beaten

The control function of aspect：First, in the starting process and power generation process of starter-generator, timesharing carry out a variety of working conditions it
Between switching；Secondly, under each working condition, the control to running statuses such as the input-output powers of each phase winding is realized；The
Three, there is provided the various protection controls such as overvoltage, excessively stream, under-voltage.Controller realizes control function, it is necessary first to senses module offer table
Show the state parameter of the running status of starter-generator.Carried out in detail below in conjunction with controller and sensing module two parts content
Explanation.
Fig. 5 shows the sensing module and controller architecture schematic diagram of starter-generator.By sensing the position in module
Inductive module 301 can detect each phase winding of stator among main motor relative to the angle of rotor axis, so as to supply controller
Judge whether each phase reaches the turn-on angle and shut-off angle；The location sensitive module can use optical position sensitive switch, described
Optical position sensitive switch includes fluted disc and optical sensor, and the sensor is fixed on the casing of main motor, and the tooth
Disk is installed with rotor coaxial, and the Teeth Number is identical with the salient pole number of rotor.The location sensitive module can also use phase
Inductance induction installation, inductance measurement coil is set with around ground with each phase winding of stator, due to test the inductance value of coil by

Starter-generator can optionally cut different work shapes in the running from starting process to power generation process
State, generally can be divided into initial start up state, stable power-assisted state and generating state, Fig. 6-Fig. 8 is that starter-generator state is cut
Change flow chart.Require that controller uses different control strategy and control method under different working conditions.Controller determines institute
The parameter of incision working condition foundation includes engine speed, battery system state and throttle.In starting process,
Rotor makes the rotating speed of engine start from scratch rapid lifting, reaches predetermined engine idle rotational in rotor（General 800r/
min）It is in initial start up state all the time before.Controller control starter-generator is in electricity in whole initial start up state
Dynamic model formula, the starter as external output torque work；When the rotating speed of engine rises to more than idling, controller can be with base
In battery system state and driving operation state parameter, stable power-assisted state either generating state is cut in control respectively,
Starter-generator is in electric model in power-assisted state is stablized, and starter-generator operates in generating mould under generating state
Formula, energy is provided to battery system as generator.
Under initial start up state, stable three kinds of working conditions of power-assisted state and generating state, controller and then it is directed to
The running status of each phase switch conduction and shut-off and prevent overvoltage, excessively stream, under-voltage be controlled.Controller is in various work shapes
Controllable running state parameters include turn-on angle recited above and shut-off angle, and current chopping threshold value under state.
Under initial start up state, because rotor speed is very low, counter electromotive force is substantially zeroed, and the electric current of each phase winding rises
Only limited by winding self-resistance and self-induction, the excessive trend of phase current is presented.Therefore need to control phase current to be no more than
Upper threshold, so as to avoid impact torque excessive in starting process.Now controller is adjusted using Current cut control mode
Phase current.In Current cut control mode, when rotor-position is between turn-on angle and shut-off angle, controller becomes power
Switch conduction in parallel operation, so as to which phase current is risen near current chopping limit, limited in phase current more than or equal to current chopping,
The switch in the power inverter is then turned off, declines phase current, until phase current is beaten again again after being limited less than current chopping
Drive the switch.Phase current is so set to be maintained near the current chopping limit.
After the rotating speed of starter-generator exceedes engine idle rotational, then controller according to battery system state and
Driving operation state parameter, timesharing switch in the case where stablizing power-assisted state and generating state.Wherein, according to the battery tension of detection
Size, judging that it is in allows power-assisted scope still to allow generation range.When in allow in the range of power-assisted when, now battery
Energy storage allow starter-generator be motive provide power torque output, now according to throttle, judge whether to locate
In throttle on earth；In throttle on earth in the state of, then controller control starter-generator be in electric model, so as to provide
Power-assisted, and be not in throttle on earth state when, starter-generator enter shut down standby mode.On the contrary, allow when battery is in
Generation range, then according to throttle, throttle not on earth when control starter-generator enter power generation mode, and in throttle on earth
When, in order to ensure the power output of engine, control starter-generator, which is in, shuts down standby mode.
In the case where stablizing power-assisted state, whether controller exceedes control mode switching threshold value according to the rotating speed of rotor, in electric current
Switching is performed between chopper control mode and Angle-domain imaging mode.When the rotating speed of rotor switches threshold less than Electronic control mode
During value, circuit is caused to damage in order to avoid producing too high phase current, still using Current cut control side presented hereinbefore
Switch conduction and closure in formula control power inverter, so as to which phase current size is maintained at into a predetermined safety value scope
It is interior.And after being increased to above Electronic control mode switching threshold with the rotating speed of rotor, due to phase current cycle time and motion
The increasing of electromotive force, phase current peak-fall, it is no longer necessary to perform Current cut control mode, but need to increase effective phase
Electric current transfers to use angle control mode to improve the output under electric model.Under angle control mode, controller adjustment
The control to winding phase current size is realized at the turn-on angle and shut-off angle, and then controls power output.By will be described open-minded
Angle shifts to an earlier date, and extends and opens the cycle, so as to increase the peak value of phase current, so as to improve the virtual value of phase current.And for closing
For the angle of rupture, with the increase at shut-off angle, it can influence to enter the size of current that inductance declines area, decline area's phase current in inductance
Rate of change is negative, can produce negative torque, reduces system and contributes.In order to determine the turn-on angle of optimization and turn off angle, controller is pre-
First setting speed, battery tension and turn-on angle, the mapping value pair for turning off angle angle, according to the current rotating speed and storage detected
Cell voltage, inquire about the mapping value pair and determine currently employed turn-on angle, shut-off angle angle, and it is open-minded determined by application
The conducting and disconnection switched in angle, hold-off angle control power inverter.

Equally employ the control mode of segmentation switching.When engine speed is less than Generation Control mode switching threshold, electricity can be used
Flow copped wave and angle control complex controll mode.Wherein Current cut control can ensure that power inverter is abundant, reliable work
While work, the percussion of phase current is reduced, and angle control can adjust phase current and output voltage.Current chopping and angle
Degree controls complex controll mode according to rotating speed, output voltage and turn-on angle, turns off the mapping value pair at angle, chooses the turn-on angle of optimization
With shut-off angle range, and the size of excitation copped wave threshold value control exciting current is used so that exciting current, which is no more than, to be born
Preset range, so as to reach control generate electricity output target.And when engine input speed is greater than or equal to Generation Control side
After formula switching threshold, due to the rise of rotating speed, it is gradually obvious to move the influence of potential, and excitation time shortens, and causes to encourage
The peak value of magnetoelectricity stream does not reach copped wave limit, therefore in order to ensure the stabilization of generated output, controller transfers to switch to angle position
Control model, power output is adjusted by adjusting the size of turn-on angle and shut-off angle.In power generation process, specifically exporting
Under power, the optimum value at angle and the relation unobvious of rotation speed change are turned off, thus can among Angle-domain imaging pattern
To be chosen and kept specific fixed optimize to turn off angle according to power output.And turn-on angle and power output presentation are better
Good linear relationship, therefore controller can reflect after it is determined that optimizing shut-off angle according to rotating speed and power output inquiry
Penetrate value pair and adjust the turn-on angle of optimization in real time, controller is according to fixed optimization shut-off angle and the optimization adjusted in real time
Turn-on angle respectively mutually switchs to control in power inverter.
