摘要 针对带外界未知扰动的二阶不确定非线性系统,设计非奇异的模糊自适应终端滑模跟踪控制器。利用Lyapunov稳定性理论设计参数的自适应更新规则。该控制器能保证闭环系统的稳定性并且跟踪误差及其导数在有限时间内收敛到原点的一个邻域。数值仿真的结果也验证了本文控制方法的有效性。 This paper presents an adaptive terminal sliding mode tracking control design for second order uncertain nonlinear systems. By utilizing Lyapunov stability theory, the parameter update laws are derived. The proposed controller combines a continuous non-singular TSM so that closed-loop stability and finite-time convergence of tracking errors can be guaranteed. At last, numerical simulations are done to show the effectivenessof the Drooosed method.
