摘要
针对一类非线性离散时滞互联系统的T-S模式,研究其分散容错控制问题.利用分散化并行分布补偿算法(DPDC)设计模糊分散控制器,结合Lyapunov稳定性理论,应用线性矩阵不等式(LMI)方法得出系统执行器发生故障时系统仍能保持稳定,且具有H∞性能指标的充分条件.最后,通过数值仿真进一步验证所提方法的有效性.
The problem of decentralized robust H∞ fault-tolerant control is investigated for the T-S model in discrete-time interconnected systems with time-delays. The scheme of decentralized parallel distributed compensations is used to design fuzzy controllers. A sufficient condition for state feedback decentralized robust H∞ stabilization is presented via Lyapunov function and linear matrix inequality. Finally, the simulation results show the effectiveness of the proposed methods.
