【摘要】 简单自适应控制的算法与被控对象的结构无关,因此可将其用于具有一定非线性的离散时间被控对象．在适应律的计算中引入一种新的二次型性能指标,使控制律的计算简单实用,且克服了要求被控对象为几乎严正实的条件．仿真结果和控制实例都表明了该方法具有良好的跟踪性能．更多还原

【Abstract】 The algorithm of simple adaptive control has nothing to do with the structure of the controlled plant, so it can be used to control the nonlinear discrete-time plant. A simple adaptive control algorithm is obtained by a new quadratic performance index, which is simple and applicable, and overcomes the almost strict positive realness condition imposed on the controlled plant. Simulation and experiment results show the good tracking performance of the presented approach.更多还原
