Design of Shipborne Radar Turntable Servo System

Abstract

: In view of the high attitude stability requirements of shipborne radar turret under sea conditions, the hardware and software of the two-axis shipborne radar turret servo control system were designed.DSP chip TMS320F2812 and FPGA chip were used as the servo control core for controller design, and Copley motor drivers were used to drive the motors. The control software used the "current + speed + position" triple closed loop control method and PID control algorithm was developed with CCS3.3 development platform. The system triple closed loop control model was established and simulated with the Simulink module of Matlab, and the result of 30 ms response time of the system was derived. Finally, the experimental verification shows that the design of shipborne radar turntable servo control system meets the design specifications.
