伺服系统的辨识与非线性PID控制

s to servo system is a nonlinear, many parameter and strong coupling system, the method of parameter identification is used to get the mathematical model of servo system, through the model test shows that the model matches up to the practical model. To cope with the deficiency of the general PID controller in industrial control field, this paper introduces a kind of nonlinear PID controller, and use it to control servo system. Digital simulation results show that the nonlinear PID controller is distinctly superior to the general ones.
