摘要
时滞导致控制力的不同步实施，不仅降低控制系统的性能，而且会使动力系统不稳定。针对这个实际问题，本文提出一种时滞补偿控制算法。控制律采用基于Ｌｙａｐｕｎｏｖ稳定准则的离散瞬时最优控制律。利用卡尔曼最优滤波作状态估计，对状态变量向前作一步最优预测。导出了适用于离散瞬时最优闭环时滞补偿控制算法理论公式。
Time-delay causes unsynchronized application of control forces which may not only dagrade the performance of the control system but also even induce instability to the dynamics system. In view of this practical problem, a timedelay compensating control algorithm is developed in this paper. The control law adopts that of the discrete instantaneous optimal control based on Lyapunovs criteria for stability of a dynamic system. The state vector is estimated using by Kalman filter equations. The state vector is predicted forward. The timedelay compensating control algorithm is derived which is suitable for discrete instantaneous optimal ClosedLoop control.
