摘要
针对工业控制领域对调节阀控制精度和稳定性的要求,设计一种基于MSP430单片机的智能阀门定位器。定位器采用MSP430F5438为核心控制器,执行单元选择高速开关电磁阀,控制算法上采用模糊控制整定PID参数。定位器除可以精确定位外,还具有自整定、自诊断、阀位输出等多种附加功能。在对系统的设计原理、控制要求进行简要说明后,依据模块化设计方法对硬件电路及软件进行了设计。实验结果表明,该系统具有控制精度高、稳定性好、功能丰富、智能化程度高以及便于维护等特点。
In allusion to the control precision and stability requirements of the regulating valve in the industrial control field,an intelligent valve positioner based on MSP430 SCM is designed. In the positioner,MSP430 F5438 is used as the core controller,the high-speed switching solenoid valve is selected for the execution unit,and the fuzzy control is used in the control algorithm to tune the PID parameters. In addition to the function of accurate positioning,the positioner also has various auxiliary functions such as self-tuning,self-diagnosis and valve position output. After a brief description of the system ′ s design principle and control requirements,the hardware circuit and software were designed according to the modularized design method. The experimental results show that the system has the characteristics such as high control precision and stability,rich functions,high intellectualized degree,and easy maintenance.
