研究了非线性系统的学习控制方法 .首先 ,对学习控制方法在目前发展中所存在的一些问题进行了分析 ;在此基础上 ,通过引进新的 (λ ,ξ) 范数及新的算法 ,克服了这一理论研究中所存在的一些困难 ,避免了以上问题的出现 ,获得了控制算法全局收敛和目标跟踪精度较高的结果 .而且对所给算法的可实现性问题进行了分析 This paper studies the learning control method of nonlinear system.Firstly, some problems existing in the current development of learning control method are analyzed. Based on this, by introducing new (λ, ξ) norm and new algorithm, Overcomes some difficulties in this theoretical study, avoids the above problems, and obtains the result of global convergence of control algorithm and high accuracy of target tracking. Moreover, the feasibility of the proposed algorithm is analyzed
