Research on the intelligent PID control method of the electro-hydraulic servo system of the aircraft steering gear

Abstract： An intelligent PID control method is introduced to solve the problem that the parameters of PID controller are difficult to be adjusted in the electrohydraulic servo system of aircraft steering gear.This method combines the advantages of particle swarm optimization (PSO) and PID controller,and optimizes PSO by using the selection strategy of bee algorithm,which adapts to the requirements of nonlinear dynamic control environment of aircraft servo system.The experimental results show that the intelligent PID control method of the electrohydraulic servo system of the aircraft rudder can meet the requirements of the system control performance,and has better tracking effect than the traditional PID controller.
