【摘要】 在分析交流异步电动机数学模型的基础上,提出了交流异步电动机控制系统仿真建模的新方法。在Mat lab/Simulink中,建立独立的功能模块,再进行功能模块的有机整合,搭建交流异步电动机无速度传感器直接转矩控制系统的仿真模型。仿真结果证明了该方法的合理性、有效性,为实际电机控制系统的设计和调试提供了新的思路。更多还原

【Abstract】 Based on the mathematical model of AC asynchronism motor,a novel method for modeling and simulation of AC asynchronism motor control system in Matlab was proposed.In Matlab/Simulink, the independent functional blocks were modeled.By the organic combination of these blocks, the model of speed sensorless direct torque control system can be established easily.The reasonability and validity are testified by the simulation results and this novel method offers a new thoughtway for designing and debugging actual motors.更多还原
