摘　　要：对有限转角直流无刷力矩电机及其控制系统进行研究,分析了电机模型和闭环PI控制模式模型的工作原理,着重讨论了电流环闭环PI控制模式对电机控制系统性能的影响。利用SG软件建立模型,通过仿真试验和实际测试,对比实际电流和仿真电流的上升时间、超调量和稳定电流等参数,验证了仿真模型的正确性,该仿真控制模型应用于实际系统中具有电流响应快速平稳、超调小、无静差等特点,为电机控制系统的设计提供一种新的思路。The limited angle brushless DC torque motor and control system were researched, working principles of the motor model and closed loop PI control model were analyzed, and focused on the analysis of the PI control mode of the current loop on the impact of the system. Using SG software to build model, through the simulation and practical test, comparing the actual current and simulation current rise time, maximum overshoot, steady current and other parameters, verify the correctness of the simulation model. The simulation model has small overshoot, fast and smooth current response without static error eharacteristies when used in actual systems, which provides a new method for the design of motor control system.
