| 摘 要： | 对具有未建模动态和外界干扰的随机系统,利用修正的鲁棒投影估计,采用低阶模型设计控制器,建立了全局稳定的自校正控制算法,且适合于非最小相位系统。此外,将未建模动态与外界干扰对系统的影响用Ｈ∞范数解析地刻划出来。仿真研究表明了这种方法的有效性。

| Abstract: | In this paper,a novel robost self tuning algorithm is developed for minimum and nonminimum phase system in the presence of unmodeled dynamics and external disturbances by means of the project estimation with mapping modification.The robust stability of the proposed algorithm is proved.Otherwise,the relationship between the unmodeled dynamics and the variance of the predicted error is characterized.Both theoretical analysis and simulation study show the effectiveness of the method. |
