摘要
研制了某型直升机并联舵机自动加载测试系统,用带编码器的交流伺服电机及其驱动器实现电动加载。为解决舵机有限转角小旋转扭矩的精准动态加载问题,伺服驱动器控制参数设置非常关键。在简述测试系统总体结构和伺服驱动器选型的基础上,详细介绍了电机控制模式、电机转速限制方法、电机手动操作界面、编码器分频脉冲设定、闭环复合控制实现等伺服驱动器控制参数的设置方法。实物验证表明:加载测试系统扭矩和位置控制精度均较高,可满足测试要求。
A helicopter parallel actuator automatic loading test system is developed. AC Servo Motor, which has embedded encoder, and AC Servo Driver are used to construct electric loading scheme. In order to solve small torque precise dynamic loading problem under the circumstances of actuator limited rotative angle, servo driver control parameter settings is essential. The overall structures of test system and servo driver type selection are briefly introduced in this paper. AC servo driver control parameter setting methods, such as the motor control mode, motor speed limit method, motor manual operation interface, encoder frequency pulse points set, compound closed-loop control method, are introduced in detail. Physical evidence shows that torque and position control precision of load testing system are high, and load testing system can meet the test requirements.
