【 摘 要 】

In any control loop of a process plant, the motorized valve, used as a final control element, may be required to be positioned according to the set point decided by the process requirement. There are various types of position control techniques of a motorized valve. The position control systems used in different applications need to meet the high performance, accuracy and reliability to achieve the desired output. Microcontrollers can be used as suitable means for meeting these needs. In the present paper, a position control scheme of a motorized valve has been described using microcontroller-based configuration for controlling stepper motor as actuator. The final calibration data reported in the paper reveal the linearity and reliability of the control system.
