Description
Technical Field
The invention relates to a regenerative braking technology of a motor system of a super capacitor, in particular to a controllable regenerative braking system based on the super capacitor-energy consumption resistor and a control method thereof.
Background
The control problem of the motor speed when the motor driving system recovers the kinetic energy to the super capacitor is worth paying attention. If the motor drive system utilizes super capacitor regenerative braking, the deceleration is very fast when the motor speed is high because of the induced electromotive force V on the busbusProportional to the motor speed. When V isbusLower than the super capacitor voltage VcapIn time, the kinetic energy of the motor can not be converted into the electric energy of the super capacitor, and the motor can not be braked. This is not allowed in many motor drive applications, such as electric cars, elevators, etc. The dynamic resistor can ensure that the dynamic braking can be carried out when the motor speed is at any value, so that the dynamic resistor can be used for braking when the motor speed is lower. In order to ensure smoothness of the motor drive system during braking, comfort of passengers and the like, it is desirable that when the braking coefficient is fixed, the braking torque for decelerating the motor should be constant, that is, the acceleration of the motor should be a negative value, and the motor should not cause a jitter in the motor speed when switching from the supercapacitor-based braking mode to the resistance-based braking mode.

in the above formula, the condition VbusIs the bus voltage of the positive and negative buses, VthIs a capacitive boost bridge ScThreshold voltage of VcapIs the voltage of a super capacitor, VhighIs the lithium battery voltage. Vbus≤VthRepresenting bus voltage VbusLess than or equal to the threshold voltage V of the booster circuitthAt the moment, the kinetic energy of the motor system cannot be stored into the super capacitor continuously; vcap≥VhighVoltage V representing a supercapacitorcapGreater than or equal to the voltage V of the lithium batteryhighAt the moment, the capacity of the super capacitor is full, and the kinetic energy of the motor system cannot be stored into the super capacitor continuously; the two conditions are in the relation of OR, namely, if any one condition is met, the specified trigger condition is met.
As shown in fig. 2, the composite control unit in this embodiment includes a mode switching controller OMSC, a first active disturbance rejection controller ADRC1, a second active disturbance rejection controller ADRC2, and a mode switching controller OMSC implemented by software or hardware, where the mode switching controller OMSC is configured to switch to the dynamic resistor braking mode when a specified trigger condition is met during braking of the motor system, the first active disturbance rejection controller ADRC1 is configured to control the motor speed based on the super capacitor braking mode, and the second active disturbance rejection controller ADRC2 is configured to control the motor speed based on the dynamic resistor braking mode.
The first active disturbance rejection controller ADRC1 is used to control the motor speed based on the super capacitor braking mode. As shown in fig. 2, the input of the first active disturbance rejection controller ADRC1 is the motor speed vbAnd a specified reference velocity vgThe output is used for controlling a capacitor voltage reduction bridge S through a PWM generatorec. Second active disturbance rejection controller ADRC2 is used to control motor speed based on the dynamic resistive braking mode. As shown in fig. 2, the input of the second active disturbance rejection controller ADRC2 is the motor speed vbAnd a specified reference velocity vgThe output is used for controlling the energy consumption voltage reduction bridge S through the PWM generatorer. It should be noted that the first active-disturbance-rejection controller ADRC1 and the second active-disturbance-rejection controller ADRC2 are both active-disturbance-rejection controllers, and the active-disturbance-rejection controllers are conventional controller technologies, so detailed descriptions thereof are omitted here.
Mode switching controller principle: the mode switching controller based on event trigger is used for managing controllers connected with the mode switching controller, and the controllers are activated when a trigger condition is met, and the core problem is how to design the trigger condition. In this embodiment, the mode switching controller OMSC operates on the principle that when the trigger condition is satisfied, the second active disturbance rejection controller ADRC2 is activated, and the braking mode of the motor system is switched from the super capacitor braking mode to the dynamic resistor braking mode. When V isbus≤VthWhen the braking energy can not be stored in the super capacitor, the motor system can not continue to brake, or when V iscap≥VhighThe motor system is also unable to continue braking. Energy consumption resistor RerAlthough energy can be dissipated all the time for braking, the energy cannot be stored, and the kinetic energy of the motor system is converted into the energy consumption resistor RerThe heat energy of the heat is dissipated. Therefore, the super capacitor should absorb the braking energy as much as possible until the super capacitor cannot store the energy, and then the braking mode is switched from the super capacitor braking mode to the dynamic resistor braking mode. If the trigger condition of the mode switch controller OMSC is fulfilled, the second ADRC2 will be activatedActive, the first active disturbance rejection controller ADRC1 will be turned off and the motor system braking mode is switched from the super capacitor braking mode to the dynamic resistor braking mode. The higher the charging voltage, the faster the super capacitor absorbs energy, and the motor stores the bus voltage V before storing the energy generated during braking into the super capacitor voltagebusBy means of a capacitive step-up bridge ScIs boosted to a high voltage VhightHowever, the boost module has a threshold voltage VthIf V isbus≤VthThe boosting module loses the function, the braking energy cannot be stored in the super capacitor, and the bus voltage V is generated when the motor brakesbusThe braking mode is directly proportional to the motor speed, namely the bus voltage is higher as the motor speed is higher, the boosting module loses the effect when the motor speed is lower than a certain value, and at the moment, the mode switching controller needs to switch the braking mode from the super capacitor mode to the energy consumption resistor mode.
In order to prove the performance of the controllable regenerative braking system based on the super capacitor-energy consumption resistor and the application method thereof, a series of experiments are performed in the motor transmission system in the embodiment, and the experimental results are shown in fig. 3. Fig. 3(a) shows the braking effect in the case of braking by the super capacitor, fig. 3(b) shows the braking effect in the case of braking by the dynamic resistor, and fig. 3(c) shows the desired braking effect. It can be seen from the figure that when the motor is braked based on the super capacitor, the motor speed is greater than 3r/s, the braking effect is obvious, the motor speed is lower than 3r/s, almost no braking effect exists, the motor only needs 0.2s to decelerate from the maximum speed to 3r/s, when the motor speed is lower than 3r/s, the motor only can decelerate by means of friction force, and the time consumed for decelerating from 3r/s to 0r/s exceeds 6 s. However, the motor speed can be braked by means of dynamic resistance at any value. Therefore, in order to control the speed of the motor in the whole braking process, the super capacitor and the energy consumption resistor R are required to be usederIn combination with when Vbus>VthWhile braking by super capacitor, when Vbus<VthTime-dependent power consumption resistor RerAnd (5) braking.
In summary, in order to solve the problem of speed controllability of the motor driving system based on the super capacitor during regenerative braking, the prior art only considers the utilization of the super capacitorThe capacitor and the lithium battery form a hybrid power supply to drive the motor system, and the speed control problem of the motor during regenerative braking is not considered. Therefore, the embodiment provides a hybrid controllable regenerative braking scheme based on a super capacitor and an energy consumption resistor, and the hybrid controllable regenerative braking scheme comprises a circuit topology structure and an undisturbed switching composite control method. The whole speed of the motor can be controlled during regenerative braking, and the two braking modes are switched without disturbance to the speed. When a circuit topological structure is designed, an independent energy recovery circuit is designed for a super capacitor, meanwhile, an independent energy dissipation circuit is also designed for an energy consumption resistor, when a motor starts to brake, kinetic energy of a motor driving system is firstly stored in the super capacitor, and meanwhile, current flowing to the super capacitor is controlled to control the speed of the motor, when the speed of the motor reaches a certain value, a braking mode is switched from a regenerative braking mode based on the super capacitor to an energy consumption resistor dissipation braking mode, and at the moment, the current flowing through the dissipation resistor is also controlled to control the speed of the motor. The switching of the two braking modes will inevitably disturb the speed control of the motor, and in severe cases, the system may be out of control, for this embodiment, a second active disturbance rejection controller ADRC2 is designed, which has the same input parameters and control principle as the first active disturbance rejection controller ADRC1, and is also based on the motor speed v after the second active disturbance rejection controller ADRC2 is activatedbAnd a specified reference velocity vgOutput is used for control signal and controls energy consumption step-down bridge S through PWM generatorerTherefore, the purposes of no jitter of the control quantity and undisturbed switching during switching are achieved.
The foregoing is merely a system framework for the present invention and is not intended to limit the invention in any manner. Those skilled in the art can make many possible variations and modifications to the disclosed embodiments, or modify equivalent embodiments, without departing from the scope of the disclosed embodiments. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention should fall within the protection scope of the technical scheme of the present invention, unless the technical spirit of the present invention departs from the content of the technical scheme of the present invention.
