Aiming at the problem of time delay in the networked control system, by using the nonlinear approximation of the fuzzy control algorithm，and Smith forecast compensation. A kind of controller based on fuzzy adaptive PID with new Smith predictor is presented. This controller is easy to be implemented. Then using Matlab/simulink simulation software, the simulation research on a DC motor is done, and the simulation result shows, compared with the traditional PID control and PID control with Smith predictor, the control algorithm based on the fuzzy adaptive PID with new Smith predictor can effectively improve the robustness and adaptability of the system.
