| 摘 要： | 将无速度传感器应用到转矩斜坡控制异步电动机软起动中,利用Matlab/Simulink中的电力系统工具箱对起动过程进行建模仿真,论证了理论的可行性。实验结果表明,该软起动方式的硬件结构简单,起动转矩大,能实现速度闭环控制,可以有效地减小起动过程中对电网的冲击,同时起动过程平稳,降低了对拖动系统的不利影响。

| Abstract: | Applied the speed sensor-less to torque slope control of asynchronous motor soft start,using power system toolbox in Matlab/Simulink to modeling and simulation the process of the starting,demonstrated the feasibility of the theory.The results show that the hardware structure of the soft start is simple,and high starting torque,to achieve speed closed-loop control,and reduces the impact on network effectively during the starting process,at the same time makes the start process smooth and reduces the adverse ... |
