| Abstract: | Based on the advanced quality of predictive control, this paper presents a predictive controller for canal automatic operation. The purpose is to improve the system's dynamic performances. A dynamic matrix control (DMC) model for a single canal is built; and the constant-water-volume model is adopted to control the midpoint water level of the canal; and Saint-Venant equation is used to figure out the hydraulic process. Matlab and Simulink are applied to simulate the control system; and the stability of the system is analyzed. Finally, the results indicate that the controller can build up the robustness of the system, especially has distinct effect on overcoming time lag. |
