| 摘 要： | 针对非线性函数关于未知参数是凹/凸函数的一类非线性系统,设计了基于极大极小策略的自适应控制器.与过去的具有非线性参数不确定性的系统的自适应控制器相比,该控制器能保证闭环系统输出跟踪误差渐近趋于零.最后通过对一个单摆模型的仿真验证了算法的有效性.

| Abstract: | A class of nonlinear systems was considered and the nonlinearity in unknown parameters was assumed to be either convex or concave. An adaptive controller based on a min-max strategy was designed. Compared with the past adaptive controller of systems with nonlinear parameter uncertainties, the controller can guarantee the output tracking error of close-loop systems to converge asymptotically to zero. In the end, the effectiveness of the approach is verified by a simulation of a single pendulum. |
