Electric Control Loading System is to provide drivers with force feedback force displacement following system, the inner-loop as force-loop limited by strong disturbance of position loop and the narrow system frequency width, cause the system dynamic response is poor and simulation effect of force is bad. How to retrain disturbance of position loop surplus force and expand force loop bandwidth isa key problem for this system. This paper establishedthe physical and mathematical model of motor type electric control loading system, described the method to determine the parameters of force loop(inner loop) model; According to the characteristicsof force loop, the controller of force loop was designed based on LMI(linear matrix inequality), semi-physical simulation show that the controller restrain effectively the disturbance of surplus force, extend the bandwidth and improve rapid response of force loop. and user feedback showed that Electric Control Loading System’s static and dynamic characteristics fully meet the standardmilitarysimulatorwith this paper’s control strategy.
