| Abstract: | In this paper,the problem which difficulty of reducing the overshoot is discussed.An improved algorithm for the PID-type Generalized Predictive Control is derived by adding the proportion and differential structure to the usual cost function of predictive control.By using the feedback effect of PID to improve the ability of controller,and the performance of the system is greatly improved by taking full advantage of the predictive information.The simulation results show that this control method is effective. |
