This paper presents an adaptive neural network controller (ANNC) that is used to control the speed of a separately excited dc motor deriving a centrifugal pump load and fed from photovoltaic (PV) generator through dc-dc buckboost converter. The controller is also used to track the maximum power point (MPP) of the PV generator by controlling the converter duty ratio. Such kind of controllers mus...

This paper is mainly focused on Hybrid Energy Management System (HEMS) consisting ofBattery (BT) and Super capacitor (SC). Two energy sources connected in with same DC link parallel manner the help of Bidirectional DC-DC converter, which used to separate control power flow each source. Here Permanent magnet dc motor (PMDC) as a load speed PMDC can be done by PWM method for this purpose chopper ...

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...

Brushless DC motors (BLDC) are widely used in industrial areas. The BLDC motors are driven either by indirect ACAC converters or by direct AC-AC converters. Direct AC-AC converters i.e. matrix converters are used in this paper to drive the three phase BLDC motor and it eliminates the bulky DC link energy storage element. A matrix converter converts the AC power supply to an AC voltage of variab...

This paper presents a spherical motor driven by electro-magnets that can rotate omnidirectionally with some degrees of rotation angle error independent of rotation direction. The spherical motor is composed of a spherical rotor, a semi-spherical stator, a control PC, a control circuit, and a DC power supply. The rotor has 92 neodymium magnets. On the other hand, 84 electro-magnets are arranged ...

This paper describes the use of Universal Learning Networks (ULNs) in the speed control of a separately excited DC motor drives fed from Photovoltaic (PV) generators through intermediate power converters. Two ULNs-based identification and control are used. Their free parameters are updated online concurrently by the forward propagation algorithm. The identifier network is used to capture and em...
