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...

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...
