The Technology and information development involve production process in industries using microcontroller as a brain in control process. The number  of control process with microcontroller using Fuzzy Logic method to get the function as is needed. Motors DC are used in some  equipment as a driver, not only in small scale but also in huge scale. It used in low or high speed too. The way of controlled chosen depend on the function of DC motor movement. The another method is Pulse Width Modulation (PWM). This is an effective method to controlled DC motor. This method produces square pulses which have specific comparison between high pulse and low pulse. It is usual scale from 0% to 100%. In this research, both Fuzzy Logic method and Pulse Width Modulation (PWM) method base of microcontroller ATMega 8535, both are integrated to control lthe  DC motor speed.

Mail delivery at the Faculty of Engineering Pancasila University (FTUP) has many complaints regarding the delay of mail delivery from the administrative officer to the recipient of the mail. Lack of administrative staff responsible for the delay of mail acceptance can certainly cause great disadventages to the recipient; hence this can be a big factor inhibiting the dissemination of information. As technology develops, many research on robot able to accommodate human’s work. One type of robot that has been developed is the Robot Line Follower. In order to reduce the mail delivery delay, in this research we built a Line Follower Robot using Fuzzy Logic method. Fuzzy logic applied to this robot as a determinant of Servo motor speed and distance determinant of mail delivery area. This research yields 100% accuracy for straight line, 79% accuracy for U-line, 53% accuracy for 90o turn, 94,75% accuracy for obstacle detection, 87,75% accuracy for alarm, and 92,75% accuracy for RFID card detection, and 82% accuracy for RFID Card with option menu.

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.

Pulse width modulation (PWM) is used to generate pulses with variable duty cycle rate. The rapid rising and falling edges of PWM signal minimises the switching transition time and the associated switching losses. This paper presents a DC motor speed controller system using PWM technique. The PWM duty cycle is used to vary the speed of the motor by controlling the motor terminal voltage.The motor voltage and revolutions per minutes (RPM) obtained at different duty cycle rates. As the duty cycle increases, more voltage is applied to the motor. This contributes to the stronger magnetic flux inside the armature windings and the increasethe RPM. The characteristics and performance of the DC motor speed control system was investigated. In this paper, a PIC microcontroller and a DC-DC buck converter are employed in the DC motor speed controller system circuit. The microcontroller provides flexibility to the circuit by incorporating two push button switches in order to increase and to decrease the duty cycle rate. The characteristics and performance of the motor speed controller system using microcontroller was examined at different duty cycle rate ranging from 19% to 99%.

The continuously increasing use of photovoltaic cells requires various efforts to maximize the harnessing of solar energy. This paper presents the research results of fuzzy-logic method implementation to maximize the absorption of solar energy. It is based on the optimization of solar panels position according to the sun direction. The Takagi-Sugeno method is chosen in the fuzzification stage. The control algorithm is implemented on a microcontroller ATMega-128 using BASCOM-AVR program. DC motor is used to actuate the solar panels. The results show an increase of 0.48V in the output of solar cells sensor using the fuzzy logic computation-based tracking system. The resulted tracking system proves to consume less power because the tracking process is halted while moving the DC motor continuously.

In this paper an integrated electronic system has been designed, constructed and tested. The system utilizes an interface card through the parallel port in addition to some auxiliary circuits to perform fuzzy control operations for DC motor speed control with load and no load. Software is written using (C++ language Ver. 3.1) to display the image as control panel for different types of both conventional and fuzzy control. The main task of the software is to simulate: first, how to find out the correct parameters for fuzzy logic controller (membership’s function, rules and scaling factor). Second, how to evaluate the gain factors (KP, KI and KD) by Ziegler-Nichols method. When executing any type of control process the efficiency is estimated by drawing the relative speed response for this control.

Fuzzy Logic Method

Brushless DC Motor is used frequently in industrial applications, because this type of motor has high efficiency and does not cause sparks. However, the speed control of this motor generally has a slow response to the set point and the speed is not constant when given different loads. Therefore, it is essential to design sophisticated speed control system for this motor to improve the constant speed and speed response. In this paper, fuzzy logic method for speed control system is used to give the decision of how much voltage will be added to the motor to get to the desired speed set point value, and how much voltage will be reduced if the speed of the motor passes through the speed set point. brushless dc motor speed is set with input voltage to the motor taking into account speed error and delta speed error using Fuzzy Logic, so that when the speed of the motor almost reaches the set point the input voltage to the motor is reduced so as not to overshoot until the speed of the motor reaches the set point. The results of this study gave a better response than not using fuzzy logic methods. Where at set point 270 gets response time to set point (Tr) faster 0.0002 seconds from 0.0046 seconds to 0.0044, the time to steady state (Ts) is faster 0.025 seconds from 0.04 seconds to 0.015 seconds, the maximum pass percentage (Mp) is reduced from 75% to 20%, and error speed from 1.5% to 0%. And for a trial load at t=0.025 seconds in set point 270 with a load of 4Nm responds to the set point back for 0.014 seconds.
