摘　　要：为解决传统数字阀驱动复杂、可靠性低、控制驱动器体积大等问题,设计了一种偏心拨杆数字阀用位置控制驱动器。该控制驱动器以STM32F103RET6作为控制核心,以LMD18200智能模块作为驱动单元,采用模拟霍尔位置传感器检测电机转角位置,通过控制有限转角电机,进而实现对偏心拨杆数字伺服阀的驱动。介绍了伺服系统的总体方案、系统硬件、软件设计及控制算法,并对系统样机进行了试验。试验证明,该伺服控制驱动器集成度高,体积小,能够实现高精度、高动态的位置伺服控制。In order to solve the problem that traditional digital servo-valve is hard-driven,unreliable and voluminous,a position servo controller for the digital servo valve with eccentric paddle is designed.The controller takes STM32F103RET6 as the control unit and intelligent driver chip LMD18200 as the driver unit,uses a current sensor and a magnetic angle sensor as the sensor unit,and then drives the digital servo valve by controlling the limited angle motor.The whole design,hardware and the software of servo system are mainly described,and the prototype of the system is tested.The results show that the controller has high integrity and smaller size,and can realize high-precision and high-dynamic performance of position control.
