Block diagram analysis of speed time characteristics of a simple DC motor and modeling of a PID controller in fuzzy systems engineering

In this paper, we discuss various techniques for changing the armature voltage to control the speed of a DC motor drive. Due to the ability to provide a variable DC output voltage from a fixed AC voltage, rectifiers are used. DC motors have variable characteristics and are used extensively in variable-speed drives in fuzzy systems engineering. The two most popular PID techniques are the step reaction curve experiment and a closed-loop “cycling” experiment under proportional control around the nominal operating point. In the absence of knowledge of the underlying process, our aim to consider a PID controller as the historically best controller.
