【Abstract】 In this paper, an improved generalized predictive control with better control quality is designed for the controlled object with large inertia and large delay. Combined with ant colony algorithm, the parameters of generalized predictive control are optimized. The structure is simple and easy to realize in computer. The simulation results show that the improved generalized predictive control combined with ant colony algorithm is obviously better than the conventional PID control, which can track the set value faster and more accurately, greatly reduce the regulation time, and obtain better control effect based on the conventional GPC control.更多还原
