摘　　要：电动负载模拟器是一种能精确控制输出转矩的系统,是科学试验、工业生产中用来模拟机械负载的重要设备之一。论文分析了以永磁同步电机为加载电机的负载模拟器的工作原理,推导、构建了系统的数学模型。采用经典PID算法对转矩、电流进行闭环控制,并引入前馈补偿,抑制由被加载对象主动运动引起的多余力矩,实现系统的快响应、高精度控制。最后借助MATLAB/Simulink验证系统可行性,参照负载模拟器的评价指标体系讨论系统性能。Electric load simulator is a precise control of the output torque of the system, is a scientific experiment, industrial production equipment used to simulate one of the important mechanical load. This paper analyzes the permanent magnet synchronous motor is loaded with the motor load simulator works derived construct a mathematical model of the system. Classic PID algorithm torque, current loop control, and before the introduction of feed-forward compensation, inhibit the excess torque load objects from being active movement caused by the fast response of the system to achieve high-precision control.Finally With MATLAB/Simulink to verify the feasibility of the system, the reference load simulator evaluation system discussion system performance.
