Automobile electronic throttle control system is a changeable and complicated process.It is difficult for the conventional PID control strategy to achieve the ideal effect due to the impacts of some unstable factors.In the paper,the PID controller was optimized based on the particle swarm optimization(PSO) algorithm and the PSO-PID compound control strategy was designed.The parameter setting and algorithm process design for the electronic throttle PSO-PID controller was completed.The simulation analysis showed that the electronic throttle PSO-PID compound control strategy can reduce the overshoot of the control system decrease the transient error,and shorten the time lag,which is applicable to the electronic throttle control system.
