Detailed description of the invention
Fig. 1 is the schematic diagram of propeller provided in an embodiment of the present invention and Engine Matching control；
Specific embodiment
The embodiment that blade quantity is 6 is chosen below, and the step of this method is described in detail.It comprises the following processes:
1) working condition of clear propeller.
According to the principal performance of current propeller, working condition mainly includes slow train, takes off, cruises, climbs.
2) working status parameter of clear propeller
The working status parameter of propeller includes:
Propeller blade-angles, revolving speed, blade angle, torque, demand revolving speed, demand blade angle etc.；
3) the control law design of propeller:
When propeller is in idling rating, using blade angle close-loop control mode.Control process is according to propeller reality
Border input requirements guarantee that propeller maintains in demand blade angular region.
When propeller, which is in, the states such as takes off, cruises, climbs, using speed closed loop control mode.Control process is root
Requirement, which is actually entered, according to propeller guarantees that propeller maintains in the demand range of speeds.
4) the control law switching condition of propeller:
When propeller transitted to by idling rating cruise of taking off, climb, state when, design slow train process control rule and turn
The switching condition of fast closed loop control laws, the switching condition are related to the input requirements of propeller.
Specific switch law is as follows:
When propeller by idling rating accelerate work to take off, climb, cruising condition when, propeller torque and revolving speed with
Engine output increases and increases, and torque is not able to satisfy requirement when to guarantee that revolution speed of propeller rises, control law
For blade angle closed loop control laws, in order to which revolution speed of propeller is out of control during guaranteeing, take off, cruise when revolution speed of propeller is greater than,
When demand revolving speed when climb mode, propeller control law enters speed closed loop control by blade angle closed loop control laws and advises
Rule.
When propeller is by taking off, climbing, cruising condition decelerating operation to idling rating when, propeller torque and revolving speed with
Engine output reduces and reduces, and when to guarantee revolution speed of propeller decline, torque is met the requirements, using speed closed loop control
Rule, design is when revolution speed of propeller is less than (demand revolving speed+limits value), using blade angle closed loop control laws.In order to prevent
Propeller speed closed loop control and the switching of blade angle closed loop control cycles formula during the work time, uses in switching condition design
Demand revolving speed+limits value method is realized, propeller is avoided to be in alternately switching state.
Propeller is when taking off, climbing, switch under cruising condition, when propeller output power changes, three kinds of states
State switching under steady working condition, propeller works state characteristic is almost the same, therefore control law does not change, and adopts
With speed closed loop control rule.
5) according to the design protection control logic of propeller works state parameter
The main purpose of propeller protection control logic is to monitor in real time to the running parameter of propeller, when normal control
When system rule and handoff procedure fail, it need to realize that the protection of propeller is controlled by protection control logic.Propeller protection control
Matching relationship between main monitoring revolution speed of propeller and torque, specific design logic are as follows:
When revolution speed of propeller is excessively high, need to design feathering relay protective scheme prevents torque too low；
When revolution speed of propeller is too low, need to design deficient fast relay protective scheme prevents torque excessive.
