基于AMESim与Simulink的电动液压助力转向系统的联合仿真

Co-simulation Study of Electro-hydraulic Power Steering System Based on AMESim and Simulink

在AMESim和MATLAB/Simulink平台上分别建立电动液压助力转向系统的动力学模型和PID控制的ECU模型,通过创建S函数实现AMESim和Simulink的接口互连。根据所建模型进行联合仿真,联合仿真结果表明,本文所建立的EHPS系统的动力学模型和控制算法是正确的。

EHPS mechanical dynamics model was created on the platform of AMESim and MATLAB/Simulink which was used to build a PID controller model, and S-function was built to connect their interfaces. The co-simulation of the model is done, and the results show that EHPS mechanical dynamics model and control algorithm in the paper are correct.
