具有有界扰动系统的间接自适应控制算法

Indirect Adaptive Control Algorithm for Systems with Bounded Disturbances

本文对具有有界扰动的线性离散时间系统提出一种间接自适应控制算法,证明了自适应闭环系统的全局稳定性。算法的一个特点是能够配置闭环极点,克服了一般自适应控制二次型性能指标中加权阵选择的困难。仿真实例表明了算法的良好特性。

This paper presents an indirect adaptive control algorithm for the linear discrete time systems with bounded disturbances and the proof of globle stability of adaptive closed loop systems is given. The algorithm real-izes the pole placement of closed loop systems and overcomes the difficulty of the weighting polynomials choice of the quadratic cost function in general adaptive control. A simulation shows the main features of the algorithm.
