Abstract
This paper describes the speed control of d.c. servo motor by PID method in loads. PID algorithm has mainly been used in industrial circles In spite of the development of various control theory. D.C. motor speed is controlled by a microprocessor (Z-80). The speed control of d.c. motor is experimented in transient and steady state. In this study, feedforward controller Is used for dealing with loads. When it is possible to measure loads, this feed forward controller is used with another controller. And also, satisfying control effect Is gotten by using it In system with loads. Therefore, It is proved through experiment that a new designed controller can control the speed of d.c. servo motor.
