Abstract
In this paper, the pure electric brake of the train and the vector control of the asynchronous motor without speed sensor are studied, respectively. The pure electric brake of the train is controlled by a combination of regenerative brake and reverse brake. The estimation method of the feedback speed is based on the Model Reference Adaptive System (MRAS), and both the traditional MRAS and the improved MRAS are analyzed. In this paper, pure electric brake and MRAS estimation are combined to get a better system. Finally, by using the improved MRAS speed estimation method, a simulation of the pure electric brake with speed sensorless control is established with MATLAB simulation software to verify the study.
