BLDC motor has very vast speed range but its speed control is difficult. In literature, there are many control techniques reported to control speed. This paper presents FUZZYSMC based speed control of BLDC motor, by combining the beneficial features of both sliding mode control and fuzzy logic. This design is compared with PI controller.Abstract- Speed control of DC Motor is vital in many applications. In this paper, an effort has been made to control the speed of the DC motor using fuzzy logic control (FLC) based on LabVIEW (Laboratory Virtual Instrument Engineering Workbench) program.A cascade structure consisting of a Generic Model Control (GMC) in the inner loop and a PID in the outer loop was used to control the speed of a DC motor. Results obtained from though satisfactory, show chattering in output speed when a load of torque 30Nm was applied.

Hence, very smooth speed control of the dc motor can be obtained by this method. Speed control of series motor 1. Flux control method. Field diverter: A variable resistance is connected parallel to the series field as shown in fig (a). This variable resistor is called as a diverter, as the desired amount of current can be diverted through this resistor and, hence, current through field coil.Read More
The paper deals with design of control for DC motor and analysis with focus on speed control. Firstly, mathematical model of DC motor was created.

The identification and real time speed control, without reverse motion, for a series DC motor is presented. The identification is performed using the transient response analysis of the mechanical and electrical subsystems of a series DC motor. A linearized model which does not include the magnetic saturation around the operating conditions is considered. Based on this model, a PI speed.Read More

DTMF based motor control is a method which uses Dual Tone Multi Frequency(DTMF) technology to control a dc motor by using a mobile phone. A call is made to the mobile phone connected to the dc motor and during the course of the call, whatever key is pressed on the mobile phone is heard at the other end.Read More
