摘　　要：针对一类具有传感器故障和未建模动态的纯反馈系统,研究其预设性能有限时间控制问题.设计无关初始条件的预设性能有限时间容错控制器.该文控制器对未建模动态有较好的抑制作用,使预设性能函数的选择与初始状态无关.仿真结果表明该文控制器具有可行性.The prescribed performance finite-time control problem was investigated for a class of pure feedback systems with sensor faults and unmodeled dynamics.A prescribed performance finite-time fault-tolerant controller was designed,and the controller was regardless of initial conditions.The controller in this paper had a better inhibitory effect on the unmodeled dynamics,made the selection of the prescribed performance function independent of initial states.The simulation results verified the feasibility of the controller in this paper.
