用MATLAB软件对电动汽车的计算机模拟

Dynamic Computer Simulation of Electrical Vehicle in an MATLAB Software Environment

提出了用先进的科学计算软件ＭＡＴＬＡＢ对电动汽车作计算机模拟的方法，充分利用了ＭＡＴＬＡＢ及其最新扩展的分支ＳＩＭＵＬＡＢ软件特有的人机对话方式的性能，根据由电动汽车各部件定义的功能框，通过菜单式的选择方式，使模拟过程具有很强的可观察性和适应性，且避免了传统计算机模拟的繁复编程过程，大大减少了工作量．此模拟方法可推广到各种动态系统。

An attempt has been made to simulate the electrical vehicle (EV) with high performance MATLAB software package. The specific interactive function of MATLAB and its subprogram SIMULAB, which is especially good for the investigation of the dynamic performance, have been fully utilized. Mathematical models for every component in EV can be modelled with the corresponding blocks. Different physicall processes including those for different types of EVs, different driving motors and batteries can be intuitively simulated by menu driven commands under various driving modes. Practical tests demonstrate that the simulation in an MATLAB environment is of better suitability and observability than that by traditional numerical computation, which is usually accompanied by complicated programs.
