Research on High Dynamic Target Electro-optical Tracking Based Improved Robust Disturbance Observer
The compound axis control technique is an effective means to improve the accuracy and bandwidth of high precision electro-optical tracking systems. However, traditional methods of lead and lag correction can not achieve ideal performance. The robust control method based on the disturbance observer (DOB) 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 of lead and lag correction, the method based on DOB can inhibit high-frequency noise and compensate for low-frequency interference better, such as frictions, and achieve better precision finally.
