应用MATLAB对装甲车辆电气系统仿真的研究

A Study on Applying MATLAB/Simulink to Simulate the Power System in Vehicle

车辆电气系统中广泛地采用硅整流器发电机,硅整流器的工作模式随时间而改变,发电机工作的约束条件多.目前现有的数字仿真方法的计算工作量大,编程困难.MATLAB语言是一个数学分析与运算软件,可以用作动态系统的建模与仿真,它有非常强大的矩阵分析与运算能力.MATLAB还是一个开放的环境,人们己经开发了许多具有特殊用途的工具箱软件.本文提出了一种对车辆电气系统应用MATLAB/Simulink的建模和仿真方法,此方法不仅编程简单,运算效率高,而且具有很高的仿真精度.

At present , the silicon- rectifying generator was applied widely in power supply systems in vehicles. The functional modes of rectifier change ate. Computation is complicated, and programme od. MATLAB simulation can select corresponding with time, and many factors restrict generator to operis difficult by using present numerical simulation methmodules from module subset, build similar system and set up Simulink simulation model according to real system, which is visual and direct and can make use of the most advanced software. The characteristic of the silicon - rectifying generator power supply system is lucubrated and is modeled and simulated by MATLAB/Simulink in this paper. This method has not only simple program and high calculating efficiency, but also high simulation precision by comparing simulation results and experiment results.
