Adaptive Pole Placement Controller with Directly Estimating Disturbance Model
-
摘要: 给出了直接在辨识器中估计扰动模型和过程模型参数的算法,扰动模型用于极点配 置自适应控制,根据内部模型原理消除未知确定扰动.由于使用了与常规方法不同的观测向 量,因而省去了分离扰动模型的计算过程.这种方法可适用于多个扰动频率的情况,且辨识器 的阶数不超过常规辨识器.分析了参数的可辨识性和系统的稳定性.Abstract: A new algorithm which directly identifies parameters of disturbance model and plant model in an estimator is given. The disturbance model is used for adaptive pole placement controller based on the internal model principle so that the disturbances can be eliminated. Because the identifing way is different from commonly used ones, it is not needed to separate the disturbance model. The method can be used in the situation where the disturbances are of many frequencies, and the degree of the estimator is not higher than that of the common one. The persistent spanning of observing signal and system stability analysis are also given.
