Fuzzy Finite-Time Command Filtered Control of Nonlinear Systems With Input Saturation
针对一类带有输入饱和的非线性系统，提出了一种模糊有限时间指令滤波反步控制方法，通过引入模糊有限时间指令滤波器和改进的误差补偿信号，实现了跟踪误差的有限时间收敛，并用实例验证了有效性。
This paper considers the fuzzy finite-time tracking control problem for a class of nonlinear systems with input saturation. A novel fuzzy finite-time command filtered backstepping approach is proposed by introducing the fuzzy finite-time command filter, designing the new virtual control signals and the modified error compensation signals. The proposed approach not only holds the advantages of the conventional command-filtered backstepping control, but also guarantees the finite-time convergence. A practical example is included to show the effectiveness of the proposed method.
