Research on turbojet engine control based on sparrow search algorithm
In order to improve the control performance of the miniature turbojet engine,a control method based on the sparrow search algorithm(SSA)was proposed to address the difficulty of online parameter tuning and parameter optimisation of the traditional PID controller.Firstly,the system identification was carried out using the experimentally obtained data of the turbojet engine in order to establish the mathematical model of the turbojet engine;secondly,the fuzzy PID controller was designed using fuzzy control;finally,the parameters of the fuzzy PID controller were optimised using SSA.The simulation results show that the SSA-based fuzzy PID control method has significant performance improvement in the speed control system of the turbojet engine,with a rise time of 0.22 s,the amount of overshoot of 8.02％,and a disturbance tuning time of 1.05 s.Compared with the traditional PID and fuzzy PID control methods,the response speed of this method has been improved by 64.1％and 43.9％,respectively,and the amount of overshoot has been reduced by 18.08％and 7.58％,and the disturbance tuning time is reduced by 52.3％and 34.4％,respectively.
