摘　　要：完成了一种航天继电器多余物自动检测系统振动台驱动器的设计。该驱动器采用C8051F020单片机为核心处理模块,CPLD为逻辑辅助器件,能够产生频率、幅值可调的正弦振动信号及脉冲冲击信号驱动振动台执行振动和冲击动作;通过实时、高精度检测加速度,采用PI算法实现了振动加速度无静差闭环控制。实验表明,驱动器能够满足航天继电器多余物自动检测系统的要求。A shaker driver of the remainder auto-detecting system for space relay is designed in this paper. A C8051F020 MCU is utilized as central controller, a CPLD as peripheral assistant component, which can produce sine wave and pulse wave with adjustable frequency and amplitude to drive the shaker＇s vibration and shock. By the highly precise real-time detection of acceleration, the closed-loop control of acceleration without steady-state error is realized based on the PI algorithm. The experiment shows that the driver is adequate for the remainder-detecting system for space relay.
