Maximum Adhesion Force Control Simulated Model of Electric Locomotive

When the traction torque of the electric locomotive exceeds the maximum adhesion force torque, the wheel will have slip/skid phenomena. To fulfill the maximum adhesion force control, a full-order state observer for estimating the adhesion torque was designed. To make DSP programming convenient, a simple control algorithm for slip velocity reference generator was proposed. Then, the simulated control model based on FOC (Field Oriented Control) was built in SIMULINK/MATLAB, and its effectiveness was verified by some specific simulation experiment and waveforms.
