Nowadays, Brushless DC motors are in high demand due to its high efficiency and other significant features. As there is no use of brushes, this type of motor is having many advantages like high torque to inertia ratio, high speed, and power density and low cost compared to conventional brushed motors. This paper determines speed torque characteristics of brushless dc motor with different load variation by using the proposed method and the developed controller. The variation in motor speed torque characteristics for half load, full load, and overloading condition is analyzed. This research has been conducted to analyze the model and compared with the simulation results which are very useful in studying the performance of motor system. The simulation is carried out in MATLAB Simulink environment.

BLDC Motor Driven Solar PV Array Fed Water Pumping System Employing Zeta Converter

This paper proposes a solar photovoltaic (SPV) array fed water pumping system utilizing a zeta converter as an intermediate DC-DC converter in order to extract the maximum available power from the SPV array. Controlling the zeta converter in an intelligent manner through the incremental conductance maximum power point tracking (INC-MPPT) algorithm offers the soft starting of the brushless DC (BLDC) motor employed to drive a centrifugal water pump coupled to its shaft. Soft starting i.e. the reduced current starting inhibits the harmful effect of the high starting current on the windings of the BLDC motor. A fundamental frequency switching of the voltage source inverter (VSI) is accomplished by the electronic commutation of the BLDC motor, thereby avoiding the VSI losses occurred owing to the high frequency switching. A new design approach for the low valued DC link capacitor of VSI is proposed. The proposed water pumping system is designed and modeled such that the performance is not affected even under the dynamic conditions. Suitability of the proposed system under dynamic conditions is demonstrated by the simulation results using MATLAB/Simulink software.

This paper deal with the speed response characteristics analysis of brushless dc motor under different load variations. BLDC drive are widely used motors now a days due to its good speed control characteristics and high efficiency which improves the performance of motor. PI controller is used in motor operation to maintain the constant speed. The analysis is carried out in three different type of load condition which are given as under load, rated load and overload conditions. The performance of BLDC motor is observed through speed, current, back emf and torque response. To evaluate the result appropriate value of Kp and Ki of controller has been taken in order to get the better result for characteristics parameter of the speed response of BLDC motor. The result are then calculated mathematically and analysed according to the load variations. The required model has been developed using Simulink Matlab and speed torque characteristics graph is also analysed using PI controller.

A Power Factor Correction (PFC) and sensor less speed control of BLDC (Brushless DC) motor using zeta converter is presented. Zeta converter is a fourth-order DC-DC converter made up of two inductors and two capacitors and capable of operating in either step-up or stepdown mode. The PFC is achieved by zeta converter. Sensor less speed control of BLDC motor is achieved and the cost and wiring of sensors are reduced. A MATLAB/ Simulink environment is used to simulate the developed model to achieve a wide range of speed control with high PF (Power Factor) and improved PQ (Power Quality) at the supply.

Control of BLDC Motor Based on Adaptive Fuzzy Logic PID Controller

This paper presents an Adaptive fuzzy logic PID controller for speed control of Brushless Direct current Motor drives which is widely used in various industrial systems, such as servo motor drives, medical, automobile and aerospace industry. BLDC motors were electronically commutated motor offer many advantages over Brushed DC Motor which includes increased efficiency, longer life, low volume and high torque. This paper presents an overview of performance of fuzzy PID controller and Adaptive fuzzy PID controller using Simulink model. Tuning Parameters and computing using Normal PID controller is difficult and also it does not give satisfied control characteristics when compare to Adaptive Fuzzy PID controller. From the Simulation results we verify that Adaptive Fuzzy PID controller give better control performance when compared to fuzzy PID controller. The software Package SIMULINK was used in control and Modelling of BLDC Motor.

High-performance multilevel inverter drive of brushless DC Motor

The brushless DC (BLDC) motor has numerous applications in high-power systems; it is simple in construction, is cheap, requires less maintenance, has higher efficiency, and has high power in the output unit. The BLDC motor is driven by an inverter. This paper presents design and simulation for a three-phase three-level inverter to drive the BLDC motor. The multilevel inverter is driven by discrete three-phase pulse width modulation (DPWM) generator that forced-commuted the IGBT’s three-level converters using three bridges to vectored outputs 12- pulses with three levels. Using DPWM with a three-level inverter solves the problem of harmonic distortions and low electromagnetic interference. This topology can attract attention in high-power and high-performance voltage applications. It provides a three-phase voltage source with amplitude, phase, and frequency that are controllable. The proposed model is used with the PID controller to follow the reference speed signal designed by variable steps. The system design is simulated by using Matlab/Simulink. Satisfactory results and high performance of the control with steady state and transient response are obtained. The results of the proposed model are compared with the variable DC-link control. The results of the proposed model are more stable and reliable.

Speed Control of PMBLDC Motor Using MATLAB/Simulink and Effects of Load and Inertia Changes

Modeling and simulation of electromechanical systems with machine drives are essential steps at the design stage of such systems. This paper describes the procedure of deriving a model for the brush less dc motor with 120-degree inverter system and its validation in the MATLAB/Simulink platform. The discussion arrives at a closed-loop speed control, in which PI algorithm is adopted and the position-pulse determination is done through current control for a standard trapezoidal BLDC motors. The simulation results for BLDC motor drive systems confirm the validity of the proposed method.
