DIGITAL SPEED CONTROL SYSTEM WITH INTEGRAL-PROPORTIONAL CONTROL
IFAC Proceedings Volumes, 1983 Abstract A microprocessor based speed control system for a dc motor drive is described. The motor is fed by a three phase fully controlled bridge the delay angle of which is set directly by the microprocessor. To control the speed of the drive a PI control algorithm is implemented first and the experimental results are obtained for changes in the ...

DEStech Transactions on Engineering and Technology Research, 2017 A DC motor is a device that converts electrical energy into mechanical energy. DC motors are inherently high-speed and low-torque. In this paper, we will use gears to solve the problem of lowering the speed and increasing the torque provided by the motor.
