Direct Current (DC) Motor Speed and Direction Controller

Abstract The direct current motor is an important drive configuration for many applications across a wide range of power and speeds. It has variable characteristics and is used extensively in variable-speed drives. The goals of this project are to control the direction and speed of a Direct Current (DC) motor. Due to the advancement of wireless technology, there are several communication devices introduced such as GSM, Wi-Fi, ZIGBEE and Bluetooth. Each of the connections has its own unique specification and application. Among these wireless connections, Bluetooth technology is often implemented and can be sent from the mobile phone at a distance of 10 meters. The speed control was implemented using Bluetooth technology to provide communication access from a smartphone. Instead, the ARDUINO UNO platform can be used to quickly promote electronic systems. And an electronics technique is called Pulse Width Modulation (PWM) is used to achieve speed control, and this technique generates high and low pulses, then these pulses vary the speed in the motor. In order to control this PWM pulse, variable resistors are used and depend on it the speed of the DC motor will increase or decrease. The variable resistor is adjusting to varying the speed of the motor, and the higher the resistance the lower the speed of the motor rotates. The direction of the motor is controlled by the relay by giving and giving a command on the virtual terminal. The speed of the motor is directly proportional to the resistance as the speed increased after the resistance also increased and vice versa. The significance of this study is practical and highly feasible from the economic point of view and has the advantage of running the motor at a higher rating in term of a reliable, durable, accurate and efficient way of controlling speed and direction control.

This paper presents an implementation of a microcontroller based boost converter to maintain constant speed of a DC motor. The optimised values namely kp,ki,kd of the Boost Converter are taken from firefly algorithm[10] and implemented using microcontroller. Pulse width modulation (PWM) is a procedure to generate changeable pulse width with different duty cycle. The PWM signal reduces the switching losses. This paper presents a DC motor speed controller where PID Controller is used where the optimized values of kp,ki,kd are taken from firefly algorithm[10]. The PWM pulse width will alter the speed of the motor. The motor voltage and revolutions per seconds (RPS) obtained at different duty cycle rates. With increase in duty cycle, further voltage is applied to the motor. This gives stronger magnetic flux in the armature windings and to enhance revolutions per seconds. The characteristics and concert of the DC motor speed control system was discussed. In this paper, a PIC microcontroller is designed with a DC-DC boost converter for the motor speed controller system. Finally to improve the graphical result we design the hardware in loop method using matlab.
