【摘要】 本文研究了一类具有非线性不确定参数的非线性系统的自适应模型参考跟踪问题。假设系统的非线性项关于不确定参数是凸或凹的。基于一种极大极小方法,提出了一种自适应控制器的设计方法。该控制器是连续的,能保证闭环系统的所有变量有界,且渐近精确跟踪参考模型。举例说明了本文结果的有用性。更多还原

【Abstract】 This paper deals with the problem of model reference adaptive tracking of a class of nonlinear systems with an uncertain parameter.The nonlinear term of the system is assumed to be either convex or concave with respect to the uncertain parameter.Based on a max-min method,an adaptive control law for the system is proposed.The adaptive control law is continuous.Boundedness of all signals of the closed loop system and the asymptotic exact tracking are guaranteed.An example is proposed to illustrate utility of the results in this paper.更多还原
