摘要
分析了时滞观测器控制的基本算法 ,给出时滞观测器控制系统的结构 .时滞观测器是利用系统过去的状态信息、状态变化的信息以及过去的激励信息来估计当前系统存在的不确定性、外部扰动 .仿真结果表明 ,时滞观测器控制系统可以很好地抑制系统的不确定性以及所受的外部干扰 .
The algorithm of time delay observer was analyzed and the structure of the control system based on time delay observer was given out. The past state information, state variational information and the past inspirit information were used to estimate the uncertainty and the external disturbance. The simulation results show that the time delay observer can observe the system uncertainties and disturbances almost immediately.
