摘　　要：提出了一种基于广义极点配置的对偶自适应控制器。有效地防止了自适应控制系统的“关断”、“终止”和“猝发”等现象。从而使自适应控制器适用于参数随机变化或快时变的系统。在每一自适应步利用谱分解和在线求解Ｄｉｏｐｈａｎｔｉｎｅ方程将系统极点配置至最优位置，使对偶自适应控制器不仅适用于非最小相位系统，同时也增强了系统的鲁棒性。A dual adaptive controller based on general poles-placing principle is presented inthis paper. The 'turn off', 'windup' and 'bursting' phenomena of adaptive control system iseliminated successfully, so this method can be used in the systems with stochastic parametersor fast time-varying systems. The poles are placed in optimal position in every adaptivestep by spectral factorization and solving diophantine equation on line, thus dual adaptivecontroller can not only be applied in non-phase systems but also increases systems'robustness.
