| 摘 要： | 通过构造出关于模型噪声和量测噪声的方差的泛函，以泛函数极小为目标，提出了随机振动控制系统中含未知噪声方差的自适应滤波优化准则，用ＤＦＰ优化方法求解出模型噪声和量测噪声的方差，从而保证Ｋａｌｍａｎ滤波的结果为最优，并应用ＬＱＧ方法实现振动控制。

| Abstract: | An optimal criterion is proposed for the adaptive Kalman filter in the control system of stochastic vibration with unknown noise variances by constructing and minimizing the functional of noise variances. The model and measurement of noise variances are evaluated by using DFP optimal method to guarantee the results of Kalman filter to be optimized. Finally, it is pointed out that vibration control can be realized by LQG method. |
