摘　　要：为了开发出轴向变量柱塞泵的驱动系统,提出了采用MSP430F149单片机作为该驱动系统MCU的设计方法。根据轴向变量柱塞泵驱动系统的特点,设计了该驱动系统的MSP430F149单片机控制电路和L297和L298N组成的驱动电路,并通过光耦隔离的措施实现了控制电路和驱动电路的连接。在此基础上,根据MSP430F149单片机定时器产生脉冲宽度调制波的特点,开发了该驱动系统的软件。通过硬软件的联合调试验证了轴向变量柱塞泵驱动系统开发的有效性。To develop the driving system ofaxial variable plunger pump, adesign method of using MSP430F149 single chip microcomputer （SCM） as micro controller unit （MCU） for this driving system is presented. According to the characteristic of the driving system of axial variable plunger pump, the control circuit based on MSP430F149 SCM and the driving circuit composed ofL297 and L298N for this driving system are designed. The link between the control circuit and the driving circuit is implemented by means of optical isolation. Based on these, according to the characteristics of the pulse width modulation （PWM） wave produced by the timer of MSP430F149 SCM, software of the driving system is developed. Finally, the validity of the development is validated by combined debugging of hardware and software.
