摘要
针对线性系统,考虑连续增益故障模型,研究了具有执行器故障的H_∞静态输出反馈可靠控制问题。首先,在执行器无故障的前提下,给出H_∞性能指标存在的充分条件,进而得出系统的静态输出反馈控制率。然后,基于执行器故障,重新设计静态输出反馈控制器,利用求解线性矩阵不等式的方法,完成静态输出反馈可靠控制器的设计。由此可靠控制器构成的闭环系统,使得当执行器发生故障时,也可使闭环系统的保持渐近稳定。最后的数值仿真验证了本文结果的有效性和可行性。
Considering the continuous fault model,for a linear system, problem of a static output feedback reliable con troller with performance was proposed. First, for the system without any faults, We can get a feedback controller, the sys tem will remain asymptotically stable, but the controller will lose efficacy when the system with actuator failures. Then, un der the actuator failures, we deduced the sufficient condition that make the system remain asymptotically again. A static out put feedback reliable controller can be obtained by using linear matrix inequality. A simulation example was given to illus trate the feasibility and effectiveness of the results.
