Multi‐actuator control with modal switching and different disturbance for scanning imaging motion compensation

Abstract Scanning imaging can be used to obtain wide field‐of‐view, high‐resolution remote‐sensing images with a telescope lens. However, the motion between the image and the sensor causes blurring during scanning, which reduces the image quality. In this paper, a motion compensation method based on...

description Abstract Scanning imaging can be used to obtain wide field‐of‐view, high‐resolution remote‐sensing images with a telescope lens. However, the motion between the image and the sensor causes blurring during scanning, which reduces the image quality. In this paper, a motion compensation method based on multi‐actuator control with modal switching is proposed. In this method, the tracking controller realizes scanning and compensation; the cooperative controller reduces the relative motion that causes motion blur, and modal switching solves the travel limitation of the linear actuator. Further, to improve the control performance, an adaptive sliding mode controller is proposed and combined with a disturbance observer. The stability theorems for multi‐actuator and modal switching are studied. Experimental results show that the accuracy, robustness, and frame rate of the proposed method improved compared with those of traditional methods. Compared with the non‐cooperative structure using a PD controller, the root mean square error is reduced by 76.61%.
