中文摘要：
为了克服电动阀门在沙漠和其他地区供电难的问题，提出了用光伏电池为蓄电池充电，用蓄电池的电能为电动阀控制系统供电，并用DSP实现全数字软件锁相环（DSPLL）控制直流电机可逆调速的脉冲宽度调节（VWM）。试验证明光伏电池能满足电动阀门的开、关所需要的电能，该方法不仅能实现整个系统的功能，而且其性能稳定可靠，减少系统的谐波和纹波成分，使整个控制系统能实时地遥控、数据采集和传输、液晶显示电机转矩，使直流电机稳速高精度控制阀门的流量。
英文摘要：
In order to address the issue of power supply for electrical valve in the deserts and other circumstances, a novel method of electrical valve power supply by accumulator is presented, which is charged by photovoltaic cell. The controlling circuits of digital software phase-locked loop （DSPLL） using digital signal process （DSP） is constructed, which is driven by the pulse-width modulation （PWM） controlled by DC motor. The experiments prove that the photovoltaic cell can provide enough energy to turn on or shut down the electrical valve. The control method not only realizes the functions of the whole system, but also runs more precisely and reliable. In addition, this method greatly decreases the harmonics and ripples of power supply systems, making the entire system realize online remote control, data acquisition and transmission, and display the torque of electrical machine on LCD precisely. At the same time, the DC motor is able to control the flow magnitude of electrical valve more precisely and steadily.
