摘　　要：针对混杂系统对象的特性,引入基于混合逻辑动态模型的建模方法,将混杂系统中的连续动态过程和离散事件过程表示为带有混合整数不等式约束的线性状态方程的形式,并且针对于混合逻辑动态模型的特点,将广义预测控制算法中的被控对象进行了相应的变动,用广义预测控制的方法去实现混杂系统的控制。具体实例的仿真结果表明,基于混合逻辑动态模型的广义预测控制能够使混杂系统的对象跟踪给定值,并且具有良好的控制品质。Aiming at the object＇s properties of the hybrid system, a modeling method based on the Mixed logic dynamic model is introduced. Continuous dynamic process and discrete dynamic process in the hybrid system were ex- pressed into state space equation with mixed integer inequality constraints. And aiming at the properties of the mixed logic dynamic model, the controlled object of generalized predictive control was changed accordingly, and the changed generalized predictive control is used to achieve the control of hybrid system. The simulation result shows the general- ized predictive control based on mixed logic dynamic model is able to stabilize hybrid system on the desired output, and the system has better character.
