DEVELOPMENT & PERFORMANCE EVALUATION OF HYBRID NN – PID CONTROLLER FOR DC SERVOMOTOR

The project focuses on position control of the DC Servo Motor MS150 Servomotor
Modular. The objectives of the project is to design and develop an advanced control
strategy for the use in the servomotor as well as to observe, evaluate and compare the
controller performances of a proposed advanced controller – Artificial Neural
Network (ANN) with the conventional controller that is Proportional – Integral –
Derivative (PID) Control. This approach is selected to investigate and evaluate the
conventional method in controlling the position of DC servomotor due to the
advantage of cost reduction, simplicity, flexibility and also provides better
performance. Based on the information obtained from servomotor modular, the
controllers are designed and simulated using MATLAB/SIMULINK to analyze their
initial performance. Finally, the performance of the controllers are compared and
evaluated and the validation is done in terms of time response, overshoot response
and steady – state error.
