摘要本文中将基于间断连续混杂系统的离散跟踪控制方法应用于网络控制系统中,提出了一种事件触发机制,并将其与间断连续混杂控制器(PCS)相结合,开发设计了一个基于事件触发机制的轨迹跟踪控制器,以达到节省网络带宽的目的。该轨迹跟踪控制器的几个组成部分都可以由间断连续混杂系统实现。通过仿真研究验证了该控制方案的有效性,并且总结了改变触发条件在轨迹跟踪性能方面会造成的影响。该轨迹跟踪控制器既能保证良好的控制性能,又能满足控制系统降低能耗和节省带宽的要求。本文中设计的轨迹跟踪控制器是针对状态已知的情况的,因此为了完善该控制方案,进一步针对状态未知的情况下的轨迹跟踪进行了研究,并且设计了一个间断连续状态观测器。87429

Title Study of Event-triggered Control Mechanism Using Piecewise Continuous Systems
Abstract In this paper, a control method for discrete tracking based on piecewise continuous systems (PCS) is applied to network control systems。 A kind of event-triggered mechanism (ETM) is proposed and combined with the PCS controller in order to design a class of event-triggered trajectory tracking controller for saving network bandwidth。 The components of the controller proposed can be realized by PCS。 Simulation study is given to demonstrate the performance of the control method, and the influence on the performance of the controller is presented by changing trigger conditions。 The event-triggered trajectory tracking controller not only exhibits good performance, but also reduces energy consumption and saves network bandwidth。 The controller proposed is only pointing at systems with known state, as a result, to improve the trajectory tracking controller, study is conducted to cope with the systems with unknown state,and a class of piecewise continuous observers is presented。
