Various method of speed control of DC motor is available in the literature. This paper presents design and implements of fuzzy logic in the speed control of DC motor. Fuzzy logic has found high application as a speed control techniques because of its ability to take into account vague and uncertainties [1]. This paper presents a MATLAB simulink model for speed control of DC motor using fuzzy lo...

The commutation process causes current ripple to be generated in the drive system of brushless DC (BLDC) motor. This, in turn, leads to output torque ripple. Mechanical vibration and acoustic noise are its influences which are undesirable phenomenon in some applications. A new method is presented in this paper which reduces torque ripple and commutation period in the entire range of motor speed...

Despite the fast growing implementation of brushless DC motor, the older brushed DC motor is still relevant in many commercial, industrial and hobbyist applications due to low-cost and simplicity. Many brushed DC motor applications require precise speed and position control, thus requiring a sensor feedback. Commonly a separate rotary encoder is required to provide speed and positional feedback...

This paper deals with the implementation of PID controller for a DC motor controller application on FPGA platform. The soft IP core of PID controller is implemented on FPGA ALTERA Quartus II platform by using Quartus II software version 10.1. The PWM signal is generated by ALTERA board, which further given to DC motor for its speed control. The soft IP core of PID controller is prototyped and v...

The on-line least square parameters (electrical and mechanical) identification method of the separately DC motor is presented in this paper. The parameters of the DC machine are time dependent; therefore, for the DC drive control the on-line parameters identification procedure is mandatory. By knowing accurately the DC motor parameters, the parameters of the DC speed and current cascade control...

In this paper a direct current (DC) motor drive system for a vehicle tracking a given route is developed. The control of the system is performed using TMS320F2808 digital signal processor (DSP). The algorithm, which is used for DC motor control, is designed using Matlab/Simulink simulation software. The generated codes are built into the TMS320F2808 directly via CCS (Code Composer Studio) by fa...

this paper presents a new control structure to reduce torque ripple in switched reluctance motor. although srm possesses many advantages in motor structure, it suers from large torque ripple that causes some problems such as vibration and acoustic noise. in this paper another control loop is added and torque ripple is de ned as an objective function. by using fuzzy sliding mode strategy, the dc...

Major constraints while using motor drive system are efficiency and cost. Commutation in the conventional DC motors is carried out by commutator which is rotating part placed on the rotor and brushes. Due to these mechanical parts, conventional DC motor consist high amount of losses. Brushless DC (BLDC) Motors are very extensively used motors these days because of its advantages over convention...
