Applying Genetic Algorithm to Tuning of Parameters of PID Controller of Motor-driven Load Simulator

摘要：

The motor-driven load simulator is commonly used to provide the aerodynamic torque acting on the rudders of a flight vehicle during their flight under laboratory conditions and to accomplish the hardwarein-the-loop simulation of the total flight control system. This paper utilizes the global optimization search capacity of genetic algorithm to optimize the feedforward compensation of a motor-driven load simulator and the parameters of its PID controller. The Matlab/Simulink simulation results, presented in Fig. 5, show preliminarily that the sine response amplitude difference in the parameters thus tuned is only 0.33％ and that their phase difference is only 0.0887, indicating that our method of parameter tuning can obviously enhance the loading precision and response frequency of the PID controller.
