The following presentation looks at the operation of control systems in general, as well as specific control systems for DC motor controls in robots. Circuits used in motor speed control, techniques for speed control, and examples of different types of control systems are shown. Finally, a description of a specific type of motor control system called a PID system is detailed, showing the mathematics of PID, the parameters, the algorithms used, possible pit falls of PID programming, and an example of a PID tuning method.
