一类约束非线性系统的自适应模糊容错控制
Adaptive fuzzy fault-tolerant control for constrained nonlinear systems
摘要
Abstract
This paper proposed an adaptive fuzzy fault-tolerant control scheme for a class of uncertain nonlinear systems.By taking the possible actuator faults into account,the control scheme adopted a novel nonlinear-mapping technique to deal with the constrained output variables,used the bounded reference signal to replace the independent argument of the unknown functions,and combined the adaptive fuzzy backstepping control technique to construct appropriate controller.The result show that all of the actuator failures can be eliminated efficiently,the system output can start from anywhere within the initial output constrained space,and the global stability of the closed-loop system is achieved.The system output can track the reference signal effectively.Simulation results show the effectiveness of the control approach.关键词
