摘要
针对带有执行器故障的离散时间T-S模糊系统的可靠控制问题提出了一种可靠控制器设计方案。与已有带有执行器故障的离散时间T-S模糊系统的可靠控制器相比,本文设计的可靠控制器采用了不同的控制架构,从而引入更多控制增益矩阵变量,并且在主要结果证明过程中提出了一种附加变量引入技术,上述措施显著降低了已有结果的保守性。此外,所得到的可靠控制器设计条件是以线性矩阵不等式形式给出的,可以很方便地通过标准数值计算软件来进行求解。最后,仿真实验结果验证了本文所提出的可靠控制器的有效性。
The problem of reliable control of discrete-time T-S fuzzy systems with actuator faults is investigated and the design scheme of a reliable controller is proposed. Compared with the existing reliable controllers, different control structures are adopted in the proposed reliable controller, which can introduce more control gain matrices, and a method for introducing additional variable is also applied in the proof of the main result. Therefore, the conservatism of the existing results could be obviously reduced on account of the underlying measures. Furthermore, the obtained reliable control conditions are given in terms of linear matrix inequalities, which could be easily solved via standard numerical software. Finally, the effectiveness of the proposed approach is illustrated by means of numerical experiments.
