中文摘要
      针对一类高阶非线性参数化系统,利用分段积分机制,提出了一种新的自适应重复学习控制方法,该方法结合反馈线性化,可以处理参数在一个未知紧集内周期性快时变的非线性系统,通过引进微分-差分混合型参数自适应律,设计了一种自适应控制策略,使广义跟踪误差在误差平方范数意义下渐近收敛于零,通过构造Lyapunov泛函,给出了闭环系统收敛的一个充分条件。实例仿真结果说明了该方法的可行性。
英文摘要
      Combining the pointwise integral mechanism with the feedback linearization approach, a novel adaptive repetitive learning control for high-order Nonlinearly Parameterized Uncertain Systems with time-varying and time-invariant parameters is proposed. It can be applied to the time-varying parametric uncertainty systems with unknown compact set, rapid time-varying,periodic and where the prior knowledge is the periodicity only, A differential-difference mixed-type adaptive law and an adaptive repetitive learning control one are constructed to ensure the asymptotic convergence of the extended tracking error in the sense of square error norm. Also, a sufficient condition of the convergence of the method is given by constructing a Lyapunov functional。A simulation example illustrates the feasibility of the proposed method
