Global Finite-time Stabilization of Nonlinear Integrator Systems Subject to Input Saturation
输入饱和下的非线性积分系统的全局有限时间镇定

By utilizing finite-time control technique, a global finite-time control scheme is proposed for a class of nonlinear integrator systems subject to input saturation. First of all, based on finite-time Lyapunov stability theory, a global finite-time recursive stabilizing controller is presented. Then by combining the saturated function with the recursive controller, a saturated controller is developed. Rigorous mathematical proof shows that under the saturated controller, the closed loop system is globally finite-time stable. Simulation results verify the effectiveness of the proposed method.
