A Controller Design for Servo Control System Using Different Techniques

203 Abstract— This paper presents and analyzes different methods of speed and position controller design for a servo mechanism system. First, the servo motors and rotating masses were modelled, and PID controller was developed to achieve the desired response. Then, under the absence of system model, both PID and Fuzzy controllers were designed to achieve the desired response. Ziegler-Nichols method was used to design the PID controller. A real-time computer was used to realize the controllers obtained from each approach using rapid prototyping technique. Finally the paper compares the results obtained from the different control techniques.
