摘要
该文考虑一类具有有界干扰和未知参数的非线性系统(1),设计出一种用于输出跟踪的输出反馈鲁棒自适应控制器.该控制器能保证闭环系统的全局稳定性,并且解决了ε-跟踪问题.仿真结果表明,所设计的自适应控制器具有良好的跟踪性能.
In this paper, a class of nonlinear systems (1) with bounded disturbances and unknown parameters is considered, and a adaptive output-feedback controller is designed for output tracking. The controller can guarantee the global stability of the closed-loop system, and can solve the ε- tracking problem. The simulations show the good track effect of the adaptive controller.
