摘要
研究了一类不确定非线性系统的全局鲁棒性输出调节问题。通过调节器的拓展方程可解性的假设,来建立非线性的内模,估计非线性未知外部扰动系统,从而将输出调节问题转化为镇定问题;结合 Lyapunov 函数和自适应理论来设计控制器,解决一类非线性输出反馈系统的输出调节问题。最后,仿真结果验证了所设计的控制器的有效性。
In this paper, the globel robust output adjustment of a class of nonlinear system is studied.By assuming that the expansion equation of the regulator is solvable, to establish a nonlinear internal model, thus, transform the output adjustment problem into a stablilization problem;Combine the Backstepping design technique and Lyapunov to design the controller, so the output adjustment of a class of nonlinear output feedback system is solved.The simulation results verify the effectiveness of the proposed controller.
