摘要
针对传统的液压助力转向系统,提出通过脉冲调制控制器、伺服旋转控制阀、转向机构等构成的电控液压助力转向系统的仿真模型。在Matlab环境中对中位开式和中位闭式电控液压助力转向系统进行仿真,通过PWM脉宽调制来调速电动机,达到节能的目的。
By improving the conventional hydraulic power steering system ( HPS), a model to simulate the electrohydraulic power steering system was presented. The model is composed of a PWM controller,a rotary servo valve and a steering mechanism. In the paper, Center-Close and Center-Open EHPS is simulated with MATLAB, respectively. Electic-motor is regulated speed to save energy though impulse-with-modulation(PWM).
