Abstract：

To improve the speed stability and the system robustness of die forging press in low-speed forging process, Gauss weighted integrated online adaptive controller was designed, and the state space equation of die forging press in low-speed forging process was built. Then, for the problems of speed switch and load mutation in low-speed forging process, Gauss weighted integrated online adaptive control scheme was given, which consisted of model predictive controller and fuzzy PID controller. In stable operation stage, the control accuracy of model predictive controller was very high, but its robustness was poor and it was unable to cope with sudden changes. Therefore, the fuzzy PID controller was designed to control sudden changes, and Gauss weighted integrated method was given to prevent system vibration during controller switching. The simulation was clarified that compared with using the model predictive controller or the fuzzy PID controller alone, when speed switch and load mutation happened, the setting time of Gauss weighted integrated online adaptive controller was shortest, and the speed tracking error was the minimum, which improved accuracy and robustness of speed tracking in low-speed forging process.
