摘　　要：混杂控制系统通常是复杂的非线性控制系统,难以用统一的模型进行建模.David和Alla提出的混杂Petri网,虽然可以解决一般混杂系统的建模问题,并得到了广泛的应用,但对于传统的如PID这类控制器,缺乏统一建模的能力.探讨了基于广义自控网系统的混杂控制方法,实现了对混杂控制器中监控器和数字控制器进行统一的Petri网建模.仿真实例设计了基于广义同步自控网系统的电加热炉控制系统,给出了可根据不同温度状态实施多种控制策略的变结构数字控制器模型,并详细分析了控制器的性能,证明了广义自控网系统具有十分强大的建模能力和广泛的应用前景.Hybrid control systems are often complex nonlinear control systems which are difficult to be modeled with a unified model.The hybrid Petri nets(HPN)proposed by David and Alla can model general hybrid systems and has been widely used.However,HPN lacks the ability of unified modeling for traditional controllers such as PID.Based on the proposed generalized cyber net system,the hybrid control method is discussed.Uniform modeling of the supervisor and digital controllers in hybrid controllers using Petri nets is implemented.In the simulation example,the electric heater control system is designed by using the generalized synchronous cyber net system.A variable structure digital controller model which can implement various control strategies according to different temperature states is given,and the detailed performance analysis of the controller is performed.It is proved that the proposed generalized cyber net system has very powerful modeling capabilities and broad application prospects.
