本文针对未知参数的最小方差控制问题,提出了一种在谨慎控制器基础上加入探测信号的控制策略。利用系统方差在参数辨识好坏时的变化调节探测信号的大小,避免了单纯使用谨慎控制所产生“关断“现象。与其它次优对偶控制相比,引入探测信号的最小方差对偶控制不仅计算量小易于实现,而且能够根据需要设计控制系统的动态性能、参数跟踪能力。This paper presents a dual control strategy with a probing signal for the minimum variance control problems with unknown parameters.The probing signal can be adjusted according to the variance change of the system to avoid the ‘turn off’ phenomenon which occurred with only caution control.Comparing with other sub-optimal dual controls,the dual control which introduces a probing signal can improve the dynamic properties and the parameters’ tracking ability to meet the requirements of the control system
