Research on Target Electro-optical Tracking Based Fuzzy Disturbance Observer Controller
The compound axis control technique is a quick and effective approach to improve the accuracy of high precision target tracking systems. However, traditional disturbance observer controller can not inhibit all-domain noises and can not achieve ideal performance. The robust control method based on fuzzy disturbance observer(FDO) is introduced in this paper, and the method is applied to the electro-optical tracking system together with the Kalman Filter. Compared to the traditional method, the method based on FDOB can inhibit high-frequency noise and compensate low-frequency interference better finally.
