基于MATLAB SIMULINK的电传动履带车辆转向性能仿真

首先采用一种简单可行的电传动方案建立了新的电传动履带车辆模型。然后在对电传动履带车辆转向行驶基本理论分析的基础上，结合鼠笼式异步电机模型及其经典矢量控制方法，分别采用独立式和差速式两种控制方案对电传动履带车辆的转向行驶性能进行了仿真分析。结果表明：采用速度控制可以很好地实现车辆转向；为使扭矩和电流平稳，参考速度应以平缓的方式给定；对不同的转向工况，应采取不同的转向模式；再生转向时产生的再生能量很大，应对其加以充分重视和利用。

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.
