Using Adaptive Control in Picture Stabilizer
Abdorreza Rahmati, Ali Khaki Sedigh, Asghar Taheri · 2006
This paper describes the implementation of picture stabilizer in 3-degree of freedom table in image stabilizer. There are two innovative aspects of this work. First, parameter estimation is used to adapt the feedforward compensation terms instead of the gains of the feedback controller, as usually is the case in conventional indirect self-tuning regulators. Second, the complete adaptive controller has been implemented with C program and PCL812 card and encoder card and motor driver for command the motors. In result one method with hybrid increase accuracy system, specially when input error signal is large and need to maximum speed control system. In this system frequency of 0.3 Hz , thus we use gyro for estimate of table position. In this paper, it is specifically implemented and demonstrated on a gyro mirror line-of sight (LOS) system
