Modeling and Simulation of Brushless Doubly-Fed Machine Based on MATLAB
Abstract: This paper describes the development process and research significance of brushless doubly-fed electric machine, analyzes the basic structure and mathematical model of brushless doubly-fed machine, and uses MATLAB to model and simulate the brushless doubly-fed motor, so that it can run asynchronously and synchronously. Observe the changes of rotor speed, electromagnetic torque and current of the brushless doubly-fed motor in these two modes of operation, and analyze the rotor speed waveform, electromagnetic torque waveform and current waveform obtained under these two modes of operation. Compared with the theory, the conclusion is that the brushless doubly-fed motor has the excellent characteristics of asynchronous motor and synchronous motor, which can be used as asynchronous motor and synchronous motor.
Key words: Brushless doubly-fed machine; asynchronous operation; synchronous operation; modeling and simulation
