Title

Speed Control of Closed Loop DC Motor Using 8051 Microcontroller

Authors

Abstract

A microcontroller has all the components a microprocessor possesses and inevitably presents ROM, RAM, Serial Port, timers, input output ports interrupts, and clock circuit. The Intel invented this microcontroller, and it operates with an 8 bit family processor. The 8051 microcontroller has extensive application in various industries and also for domestic purposes when it comes to the use. The goal of this paper is to design DC Motor's 8051 Microcontroller based Embedded Closed Loop Speed Control System to research the controlled variable's reaction to set-point changes. A tachogenerator has been used in this scheme as a speed sensor producing a back emf corresponding to the speed achieved by the DC engine. This instantaneous output voltage value is then compared to the desired voltage corresponding to the desired speed given by the tachogenerator. The resulting error is used by the microcontroller to monitor the SCR's firing angle to regulate the voltage applied to the DC Motor which, in effect, directly controls the motor speed to achieve the desired value. A continuous, closed loop velocity control system was thus achieved. In the present scheme the Proportional (P) Control Algorithm was used. Experimental findings were presented to research process velocity reaction with respect to set-point adjustments. The system is low cost and is ideal for various industrial applications, such as subway trains, trolley busses and vehicles powered by batteries.
