针对一类马尔可夫跳变系统,提出了一种基于输出反馈滑模方法的异步控制方法。由于被控系统与控制器之间不同步,采用异步控制策略。在一些实际应用中,状态变量往往难以从系统外部直接测量,这使得状态反馈技术的实现更加复杂。但是,系统始终可以访问输出信息。为此,设计了一种异步输出反馈滑动控制器,在滑动面合成中引入人工时滞,以保证MJSs的滑模动力学满足达到条件,并推导了保证系统指数稳定的充分条件。此外,还给出了优化程序对人工延迟时间进行优化。最后,通过数值模拟和实际应用验证了该方法的有效性。
A novel asynchronous control for a class of Markovian jump systems (MJSs) via output feedback sliding mode approach with an artificial time-delay is proposed. The asynchronous control strategy is adopted owing to the nonsynchronization between the controlled system and the controller. In some practical applications, the state variables are often difficult to be measured directly from the outside of the system, which makes the implementation of state feedback technique more complex. However, the output information is always accessible to the system. Therefore, an asynchronous output feedback sliding controller, where an artificial time-delay is introduced in the synthesis of the sliding surface, for MJSs is designed to guarantee the sliding mode dynamics satisfying the reaching condition, and a sufficient condition is derived to ensure the resultant system exponentially stable. Besides, a program of optimization is given to optimize the artificial delay-time. Finally, a numerical simulation and a practical application are given to validate the effectiveness of the proposed technique.
