摘　　要：本文提出一种新型的广义极点配且自校正预报控制算法。通过引人双恒等变换，推导出系统和辅助系统的自校正预报模型。它可对极点进行配置，采用独立的控制算法；通过辅助估计器以避免在解Diophantine方程时可能遇到的“病态”问题。仿真表明，由该算法构成的控制系统具有良好的动态响应和较强的鲁律性。A Kind of Generalized Pole Assignment Self-tuning Predictive Controller Algorithm is proposed.By introducing double constant alterations, we establish self-tuning predictive models of system and auxi-liary system. It can assign the closed loop poles at desired positions and adopt independent control algorithm,in which the controller parameters are adjusted by estimations of plant parameters that are separately estimated. An auxiliary estimator is developed to avoid ill-condition in solving ixophantine equation- Simulations show that controlsystems formed by the algorithm have better dynamic responses and robustness for either minimal phase plants or nominal phase plants.
