Design of Ship-Borne Antenna Servo Control System Based on ADRC

Article Preview

Abstract:

Based on structure analysis of a certain ship-borne servo control system, the target velocity is contributed to exterior unknown disturbance and the system parameter change is looked as interior unknown disturbance. The extend state observer is used to estimate the disturbance accurately with the input and output information of system response, then the controller can compensate the disturbance furthest. The simulation results show that the ADRC method has good robust performance, compared with the traditional PID controller. Without using the sensor to measure the target state, it can satisfy the system requirements with a simple structure, it shows the controller has good aspect to have good engineering function and prospect.
