Abstract:
System modeling and computer aided simula tion have been increasingly used in vehicle engineering to reduce development time, improve and simplify complex systems. A Type C Electronic Power Steering (EPS) modeling and simulation program has been developed based on Matlab. The aim of this simulation is to simulate completed system dynamic behavior regarding optimizing main parameters of system model.

Key words: EPS (Electric Power Steering); System modeling; Simulation

摘要：系統(tǒng)模型和計算機(jī)輔助仿真已經(jīng)逐漸的應(yīng)用在車輛工程中，用來減少研制時間，改善和簡化復(fù)雜系統(tǒng)。一種基于Matlab軟件的C型的電動助力轉(zhuǎn)向系統(tǒng)（EPS）的造型和模擬程序已經(jīng)發(fā)展成熟。這個仿真的目標(biāo)是仿真模擬動態(tài)系統(tǒng)的行為關(guān)于系統(tǒng)模型的主要部分的最佳參數(shù)。
