针对多变量预测控制系统,从克服Matlab仿真中数值解的弊端出发,提出了将预测模型分解离散化精确递推的方法,从而有利于预测控制相关结论的验证。同时利用Matlab的图形用户界面(GUI)环境设计了预测控制仿真平台,提供良好的交互性和可扩展性。最后给出了在该平台上的仿真实例,充分验证了平台设计的有效性。
Dealing with the multi-variable predictive control system, from the point of view on avoiding Matlab simulation errors, a new method was proposed, in which the predictive model was decentralized and analyzed accurately. It helps to prove some related conclusions of predictive control. At the same time, Graphic User Interface (GUI) of Matlab was used to design a simulation platform of predictive control, which provides good interaction and extensibility. At last, some simulation examples were given to show the effectiveness of the platform.
