摘要 针对一类具有死区非线性输入的非线性系统,同时考虑系统中存在未建模不确定项,设计了自适应控制器及未知参数的自适应估计率.该控制器使得闭环系统全局稳定且实现了输出信号对参考信号的精确跟踪.仿真结果进一步证实了该控制器能对未知死区及未建模动态进行有效的补偿。 A class of nonlinear uncertain systems with dead zone input is considered.An adaptive control scheme is proposed.With this control law and update laws the stability of closed-loop systems and the output tracking performance can be guaranteed.Simulation studies confirm our results finally.
