中文摘要：
针对自适应对偶控制算法难以克服关断现象的问题,提出了一种改进的对偶控制算法。通过协方差矩阵中特征值和当前控制量在数量级上的比例关系,按照当前控制量的大小,调整抑制作用在以控制量为中心的一定范围内,实现动态调整谨慎控制作用的控制律,使得谨慎控制的抑制作用不会因为模型失配而变得过大。仿真结果表明,这种根据实际情况而动态调整参数的对偶控制算法可以有效克服关断现象,表现出良好的控制品质。
英文摘要：
To the problem that the turn-off phenomenon is difficult to be overcome in adaptive dual control,an improved dual control algorithm is presented.By considering the ratio of the eigenvalue in the covariance matrix to the current value of control quantity,the inhibitory action is adjusted within the limits of control quantity.The cautions control law can be adjusted dynamically,preventing too large inhibitory action of cautions control in the case of model mismatch.The simulation results show that this dual control algorithm can be eliminate the turn-off phenomenon and perform excellent control quality.
