Abstract

The fixed parameters in traditional PID controller lead to poor performance. In this paper, the ideal change relationship between the error of the control object and the control parameters is analyzed and nonlinear functions are presented to form a nonlinear PID controller. The parameters are tuned with the NCD Blockset in Simulink. The nonlinear PID controller is applied to one main steam temperature control system. The simulation results show that the nonlinear PID controller has better performance and robustness than traditional linear PID controller.
