摘要: 提出了一种极点配置自校正控制器的设计方法,这种方法用两级线性辨识器可直 接获得控制器参数,无需求解Diophantine方程,也不需要辨识多余的辅助参数,而且可以消 除确定扰动的影响.由于辨识器具有低阶、线性的特点,因此有较好的收敛性.文中证明了辨 识器的有效性,给出了仿真结果.Abstract: This paper develops a new design method of self-tuning pole placement controller. In this method, parameters of the controller can be directly obtained by a two level linear identifier. It is unnecessary to find the solutions of Diophamine Equation and identify the extra auxiliary parameters. At the same time, the effect of deterministic disturbances can be eliminated. The convergence is guaranteed in this method, for the identifier is of low order and linear characteristic. The validation of the identifier is proved and the simulation results are presented.
