摘要 以异步电动机直接转矩控制基本原理为基础,利用Matlab/Simulink完成直接转矩控制系统的六边形磁链控制方法和近似圆形磁链控制方法的仿真。通过改变转速给定值,得出在不同给定条件下的仿真结果,并对仿真结果进行了具体分析。最后给出了在全速范围内两种控制方法实现平滑切换的仿真模型,仿真结果验证了两种控制方法平滑切换的可行性,对直接转矩控制技术应用于工程技术等方面有一定的实用价值。 Based on the basic principle of direct torque control of induction motor, the simulations on the two kinds of methods in this control system, such as hexagonal and approximate rotundity flux linkage control methods, are carried out by Matlab/Simulink. Through changing the given speed, the simulation results in different conditions are gained and are specifically analyzed. The simulation models, that the two control methods can re- alize smooth switching in full speed field, are given at last. The simulation results verify the feasibility of smooth switching between the two control methods, which will have a certain practical value for the direct torque control in engineering technology, etc.
