Abstract

Sliding mode control (SMC) methods rely on applying a high-frequency switching control. In networked control systems (NCS), high-frequency operations/transactions are not desirable because communication bandwidth consumption increases dramatically. This paper studies the application of event-driven self-triggered techniques to sliding mode control over networks as a means for reducing the bandwidth utilization. To this end, sliding mode control with hysteresis is adopted and control updates are forced to only occur at the hysteresis band boundary. This paper elaborates on the conditions that must be fulfilled in order to ensure such operation for the case of the double integrator system. Simulation results illustrate the presented concepts.
基于事件驱动自触发方法的双积分器系统网络滑模控制
滑模控制(SMC)方法依赖于应用高频开关控制。在网络控制系统(NCS)中,由于通信带宽消耗急剧增加,高频操作/事务是不可取的。本文研究了事件驱动自触发技术在网络滑模控制中的应用,以降低网络的带宽利用率。为此,采用带迟滞的滑模控制,并强制控制更新只发生在迟滞带边界处。本文以双积分器系统为例,详细阐述了保证这种运行所必须满足的条件。仿真结果说明了所提出的概念。
