Open & closed loop control of DC servomotor speed using P, PI and PID controller.
The system consists of a DC servomotor with microcontroller based PID controller and software. The PID controller interface with computer using RS232 communication port. The software based control system controls the speed of a DC servomotor using PID method and also evaluates the values of P, I and D.
An eddy current break applied for creation of disturbance.
The following experiments to be performed :
- Open Loop Control system
- Close loop control system including P, I and D.
- Loading effect on DC servomotor and PID control action.
- Evaluation technique of P, I and D using N- Z method.
The system consists of :
- DC servomotor with Eddy current break system.
- Optocoupler based sensor system for pulse counting.
- Microcontroller based PID Controller and data acquisition system.
- Ammeter.
- 16×2 matrix display shows values of P, I, D and pulse rate.
- Software.
