| Abstract: | A digital servo system for single gimbal control moment gyro(SGCMG) based on TMS320F2812 is proposed.Three loops control scheme consisting of current,velocity and position loop are confirmed for the control performance demands.Then three loops function is analyzed and current loop and velocity loop are designed applying frequency field design.The improved PID control method is also provided in position loop,and at last simulated for different velocity.The system can accomplish speed,high precision and stabl... |
