摘要
基于预测控制的优良品质,将预测控制中的动态矩阵控制(DMC)引入渠系自动控制,设计DMC控制器,以改良系统的动态性能.对单渠段系统建立动态矩阵控制模型,采用等体积运行方式控制渠段中点水位,用SaintVenant方程求解水力过程,并采用Matlab及Simulink软件仿真.对其稳定性等进行分析,表明该控制器能够增强系统的鲁棒性,特别对解决时滞问题有显著效果.
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.
