today, dc motors is still being used globally due to their easy speed controllability. in this article, an adaptive neuro-fuzzy inference system (anfis) controller is designed for dc motors. the main purpose of performing such task is to reduce the dc motor starting current and deleting the ripple current during starting time in considering control parameters such as: rise time, settling time, ...

This contribution deals with an optimal design of a brushless DC motor, using optimization algorithms, based on collective intelligence. For this purpose, the case study motor is perfectly explained and its significant specifications are obtained as functions of the motor geometric parameters. In fact, the geometric parameters of the motor are considered as optimization variables. Then, the obj...

the aim of the present study was to investigate the effect of endurance training on syd gene expression in motor neurons of rats with diabetic neuropathy. 12 wistar male rats were randomly assigned to 3 groups (each group 4 subjects): diabetic trained (dt), diabetic untrained (dc) and healthy control (hc). two weeks after stz injection to induce diabetes, diabetic neuropathy was demonstrated by...

This paper deals with a comprehensive survey on the topic of AC/DC & DC/DC converters for DC Motor Drives. A substantial number of different AC/DC and DC/DC topologies appropriate for DC motor drives are presented. This critical literature review brings out merits, demerits, and limitations besides giving the basic operating principles of various topologies. Keywords—controlled-rectifiers, chop...

DC motor widely used-high precision digital controls. Speed control of dc motor is achieved with smooth starter by using buck converter. Hard switching causes unsatisfactory dynamic behaviour produces abrupt variations in the V & I of the motor overcome by dc-dc buck power converter by PI controller. A separately excited dc motor is used for this simulation. The proposed system with PI control ...

Due to its excellent speed control characteristics, the DC motor has been widely used in industry even though its maintenance costs are higher than the induction motor. As a result, speed control of DC motor has attracted considerable research and several methods have evolved. PID controllers have been widely used for speed control of DC motor. In this paper the using Artificial Bees Colony (AB...
