The paper presents a methodology for developing adaptive speed controllers in a permanent-magnet brushless DC (BLDC) motor drive system. A proportional-integral controller is employed in order to obtain the controller parameters at each selected load. The resulting data from PI controller are used to train adaptive neuro-fuzzy inference systems (ANFIS) that could deduce the controller parameter...

The main aim of this paper is to control the speed of PMBLDC motor by implementing SVPWM technique in FPGA based Fuzzy controller.BLDC motors are electronically commutated. An electronic controller replaces the brush/commutators assembly of the brushed DC motor, which continually switches the phase to the windings to keep the motor turning. The controller performs similar timed power distributi...

Due to their simple structure, high efficiency, fast dynamic response, Permanent Magnet Brushless DC (PMBLDC) machines are extensively used in automation, consumer electronics, electric vehicles and medical and industrial applications. Availability of these high energy density permanent magnet materials enhances the performance of PMBLDC motor drive and also reduces the size and losses in these...

The paper presents simulation results of hybrid fuzzy logic with proportional plus conventional integral-derivative controller for the speed control of permanent magnet brushless dc (PMBLDC) motor. Although conventional PID controllers are widely used in the industry due to its simple control structure and ease of implementation, these controllers pose difficulties under the conditions of nonli...

This paper presents a hybrid fuzzy logic proportional plus conventional integral-derivative controller (FP+ID) for the speed control of permanent magnet brushless dc (PMBLDC) motor. Though, PID controllers are commonly used in practice, they have failed to perform satisfactory under nonlinearity, load disturbances, parameter variation etc. In this paper, the performance of the permanent magnet ...

In this paper, A power factor correction (PFC) based single ended primary inductor converter (SEPIC) is used to regulate DC bus voltage of voltage source inverter (VSI) to run PMBLDC motor . Permanent magnet brushless DC motor (PMBLDCM) is used in air-conditioning systems and runs at rated torque and variable speed to achieve energy conservation. The analysis, design and performance of the prop...
