H-infinifty 可变结构控制被介绍因为单个 Markov 与错配的围住标准的不确定性交换了系统;错配的围住标准的外部骚乱。给定的切换的表面上的滑动模式动力学是常规的,这被显示出,没有推动,;随机的联盟者马厩;满足 H 无穷性能。一个可变结构控制器被设计保证系统轨道在一些有限时间收敛到线性切换表面。最后,一个数字例子被解决显示出有效性;理论结果的正当。
An H-infinifty variable structure control is presented for singular Markov switched systems with mismatched norm-bounded uncertainties and mismatched norm-bounded external disturbances. It is shown that the sliding mode dynamics on the given switching surface is regular, impulse-free, and stochastically stable and satisfies H-infinity performance. A variable structure controller is designed to guarantee that the system trajectory converges to the linear switching surface in some finite time. Finally, a numerical example is solved to show the effectiveness and validness of the theoretical results.
