摘　　要：针对现有高速搜索雷达伺服系统存在角度反馈精度差、数据率低、运动响应速度慢等问题,设计了一种基于DSP控制的伺服系统。通过对整个雷达系统力矩特性的详细分析,从工程应用角度计算出系统详细力矩数值,选用高速率绝对值光电编码器作为角度反馈传感器,同时优化伺服系统电磁兼容性设计性能。实际测试结果表明该伺服系统定位精度达到0.01°,角度反馈数据率达到10kHz,速度范围为0.05°/s^180°/s,速度精度达到±5%,最高加速度达60°/s2,满足高速搜索雷达的相关应用要求。For the existing high-speed search radar servo systems have disadvantages such as poor angular feedback accuracy,low data rate,and slow motion response speed,this paper designs a servo control system based on DSP.The torque characteristics of the entire radar system are analyzed in detail,and the detailed torque values of the system are calculated from the perspective of engineering applications,use high-speed absolute value photoelectric encoder as angle feedback sensor,optimize the electromagnetic compatibility design performance of the servo system.The actual test results show that the positioning accuracy of the servo system is 0.01°,the angle feedback data rate is 10kHz,the speed range is 0.05°/s^180°/s,the speed accuracy is±5%,and the maximum acceleration is 60°/s2,meet the relevant application requirements of high-speed search radar.
