Abstract:
In order to overcome the disadvantages of the traditional PI controller, e.g., the long time adjustment and weak robust performance, an internal model PID control with integral separate, IMC PD-PID, is proposed. The key feature of the present algorithm lies in that its parameters are easily adjusted. By using the integral separate method, it not only maintains the integral effect but also decreases the overall capacity. Simulation results show that IMC PD-PID has stronger robust performance and quicker queue adjusting velocity.
