Reliable Control for Two-Dimensional Systems Subject to Extended Dissipativity
研究了二维系统在扩展耗散性约束下的可靠控制器设计问题，通过引入执行器故障模型和凸优化方法，给出了保证系统均方渐近稳定和扩展耗散性的充分条件，并用仿真验证了有效性。
The problem of reliable controller design for two-dimensional (2-D) systems subject to extended dissipativity is investigated in this paper. Considering the wide usage of Roesser state-space model, a discrete-time Roesser model is introduced to describe 2-D systems. To reinforce the reliability of the system under consideration, actuator-failure model which may severely degrade performance, or even destabilize the system is introduced. Finally, the sufficient condition for the existence of reliable controller is presented to guarantee the mean square asymptotic stability and 2-D extended dissipativity of the closed-loop system under admissible actuator failures. The gains of 2-D controller are derived by means of the convex optimization method. A simulation result is exploited to verify the effectiveness and merits of the theoretical findings.
