摘　　要：综述了一种在工业领域中使用的混杂系统建模方法,即基于混合逻辑动态MLD(Mixed Logic Dynamic)的建模方法。分析了在该建模框架下系统的可观性、可控性、形式验证、稳定性、状态估计及故障检测、最优控制和预测控制,并且以水电厂为例讨论了该方法在实际工程中的应用。基于MLD的混杂系统研究目前仍处于起步阶段,在理论上混杂系统预测控制、最优控制、多目标控制及混合整数二次规划求解都有待研究,在应用上如何根据不同问题有效地建模混杂系统也有待研究。A modeling method for hybrid system in industry fields which is denoted as mixed logical dynamic system （MLD）is introduced. Ob- servability, controllability, formal verification, stability, state estimation and fault detection, optimal control and predictive control of such systems are analyzed. The application of this method to industry fields such as hydroelectric power plant is discussed. The research of hybrid system based on MLD is at the primary stage. Model predictive control, optimal control, multi-objective control and mixed integer quadratic programming are still left to be studied in theory, and how to model hybrid system efficiently according to different applications needs to be studied in practice.
