Comparative Evaluation of Electro-Mechanical Brake Clamping Force Estimation and Sensor Compensation Control Method for High-Speed-Train
Seungkoo Baek
Abstract:Recently, with the emergence of electro-mechanical brake (EMB) devices, a control method for an electric motor to replace the existing pneumatic actuator has been studied. The clamping force estimation control method (ECM) from the rotor position of the motor is primarily used because sensor installation is difficult owing to the temperature increase of the friction surface of the brake disk. However, to accurately control the clamping force according to the change in the friction surface and hysteresis charac… Show more
