Intelligent Speed Control of DC Servo Motor Drive

The performance of Chopper fed DC motor drive with fuzzy logic controller for speed control is analyzed. Even though conventional Proportional- Integral (PI) controller for dc motor control allows good speed regulation, quick starting, braking and reversing, it is tedious to tune and difficult to control sometimes because of system nonlinearities. To overcome such problems, here a mamdani inference based fuzzy logic controller is proposed where rules are based on motor inputs which are speed error and change in error. MATLAB Simulink software is used for performance analysis.
