Product Description

Servo Controller Interfacing Open/Close Loop - Bspil-Meclab


Specification :

D.C. Position Control System
This trainer consists of a feedback control system to perform angular positioning. A 360 potentiometer forms the feedback element and a Pulse Width Modulated DC motor with gear mechanism forms the actuating element.


This trainer consists of the following:

  • 360 potentiometer.
  • Signal conditioning circuit for potentiometer.
  • DC Motor.
  • Motor driver circuit.
  • DC motor power drivers
  • ADC and DAC
  • Built in power supply.


NOTE: This trainer does not include the controller. This trainer requires a controller to perform the control action. The compatible controllers are also quoted below.

The objective of this experiment is to run the DC servomotor for required position using a digital controller. In thi case, it is a microprocessor/micro controller trainer. The digital controller performs the function of the controller by replacing the summing amplifiers 1 and 2, and the error detector. The buffer amplifiers and the power driver circuit are common for both the types of control (analog and digital).

The set point is applied through software (program). The controller reads the output of the receiver buffer amplifier (process variable) through the ADC. The position control algorithm output is then sent to the DAC. The output of the DAC is applied to the power driver circuit, to drive the motor. The motor rotates until it reaches the set point. On reaching the set point, the motor stops rotating.

NOTE: The scope of supply does not include the controller. The user has to select any one of the following optional trainers, which act as a controller
