Servo Systems

This module will provide the student with an introduction to block diagrams and the application of open-loop and closed-loop control systems in industrial robotics.  The main sections of a controller are described, as well as the categories, components, and advantages of various control systems.  The module is designed to demonstrate the principles of PID control and describe how algorithms and flowcharts can be applied to design, problem-solving and troubleshooting techniques.  In addition, the module also introduces students to the concept of fuzzy logic and fuzzy control.
