摘要
研究与设计了一种电压控制式电动助力转向系统,采用MCS-51系列中的8052单片机结合A/D和D/A转换器、信号和功率放大器及频率/电压变换器等组成控制器,通过程序实现助力电动机的电压控制,进而控制助力转矩,满足电动助力转向要求。
An electronic power steering system with voltage control has been developed. This paper presents the controller which is based on the 8052 microprocessor of MCS-51 series while combining with A/D and D/A transformer, amplifier of signal and power as well as transformer of frequency/vohage. The torque is controlled by controlling the voltage of motor. The results of the experiment show that the system can meet the request of electric power steering.
