This paper investigates an application of the fuzzy logic technique for designing the speed control of a DC motor system to damp the oscillations due to different load disturbances. The Direct Current (DC) motor with conventional Proportional Integral (PI) speed controller is evaluation. This can be easily implemented and are found to be highly effective if the load changes are small. The propo...

This paper describes the analysis and design of a low cost three phase inverter brushless dc motor (BLDC) drive.For effective utilization of the developed system, a novel direct current controlled pwm scheme (DPC)is designed and implemented.. The operational principle of the four-switch BLDC motor drive and the developed control scheme are theoretically analyzed and the performance is demonstra...

This paper presents speed control of a separately excited DC motor using fuzzy logic control (FLC) based on Matlab Simulation program. This method of speed control of a dc motor represents an ideal application for introducing the concepts of fuzzy logic. The paper shows how a commercially available fuzzy logic development kit can be applied to the theoretical development of a fuzzy controller f...

Within the appliance motor control industry there is an increasing trend to move towards using brushless dc motors. This trend is in response to recent legislation mandating improved efficiency standards in appliance applications. Brushless dc motors do however require rotor position information in order to select the appropriate commutation angle. In cost sensitive applications such as applian...

-DC brush motor undergoes rigorous performance testing to predict the failures occurring. Acceptance test levels are set with margin expected flight/operations levels and qualification test levels are set above the expected operation levels to check for the survivability of DC brush motor in space. Performance testing is important to design and integration in a planned test process in which DC ...
