Steering performance simulation for electric drive tracked vehicle based on MATLAB SIMULINK

A new simplified electric drive tracked vehicle model was built. On the basis of theoretical analysis for steering of the vehicle, making use of the asynchronous motor model and its vector space control model, simulations of the steering performance of the vehicle were made in the independent and the differential steering modes. The results are as follows. The speed control can realize the straight and steering travel. To make the torque and the current smooth, a reference speed should be given gently. Different steering modes should be taken for different steering conditions. The regenerative energy is abundant during regenerative steering, and the energy should be fully used.
