Aiming at the characteristic of parameter time-varying,nonlinearity etc in electro-hy-draulic position servo-system caused by oil spil ,oil pol ution,inert zone and hysteresis,the pa-per explored the multi-modal control strategy based on human simulated intel igent control.In the paper,it analyzed the open question of electro-hydraulic position servo-system,discussed the essential feature of human simulated intel igent control,summarized up the characteristic of multi-modal control and its corresponding control algorithm.The comparative study of simulation exper-iment in multi-modal control and PID control verified the good control quality of multi-modal con-trol.The simulation results demonstrated that compared with PID control by means of multi-modal control it could obtain better tracking performance,static and dynamic characteristics as wel as stronger robustness than PID control.
