舵机电动伺服加载控制系统的设计与研究

摘要

针对电动舵机加载要求,设计了以交流伺服电机做加载设备的舵机电动伺服加载实验台.此加载装置用于测试电动舵机在近似于真实工作环境下承受各种载荷时,电动舵机可能出现的状况.给出电动加载系统的整体结构及其工作原理,介绍所采用的抗电磁干扰措施.建立电机和力矩传感器的数学模型,给出加载实验台的静、动态性能测试结果.实验结果证实加载试验台可以满足设计要求.%An electrical servo loading test-bed for the actuator was designed based on the AC servo motor, which met the require-ments of electromechanical actuator (EMA) loading, and various problems might arose in EMA which was tested under loading of ap-proximately true working environment in test-bed. There were some merits such as analyzing whole structure and working principle of the electrical loading system, introducing various anti-emi measures, establishing mathematical model of motor and torque sensor, and also giving static and dynamic performance testing results from loading test-bed. The test result shows that the loading test-bed can meet design requirements.
