Braking Torque Analysis of Eddy Current Retarder Based on Neural Network

The mathematical model of braking torque on eddy current retarder is analyzed. Aim at the shortages that comparing real output torque of eddy current retarder at high velocity the error of the mathematical model´s computation torque is big, a braking torque model based on neural network model is proposed. The neural network model of eddy current retarder is established in terms of the braking torque´s characteristics. The existing control system of eddy current retarder is studied and a novel PWM control system based on neural network model is proposed. The capabilities of mathematical model and neural network model are compared in terms of the experiment and testify the braking torque model based on neural network model is more valid
