“…It uses active compensation method which uses phase locked loop based on the combination of 3 rd harmonic back EMF, synchronic frequency filter and second order generalised integrator. The method was used to measure the precise occurred during the commutation points in the sensor less motor drive [13].

A sensor less BLDC (Brushless Direct Current) motor speed control is performed using PSO algorithm. The PSO algorithm manages the gain value of the PID controller. The speed of the BLDC motor is provided as the feedback to the controller. The error value is calculated by predetermined speed for the BLDC motor. Wind power generator is used as the input power source for driving BLDC motor. The output power of the wind power generator varies based on the wind speed. The variable input source for the BLDC motor affects the performance of the motor. In order to regulate the input voltage of the BLDC motor, SEPIC DC-DC converter is used. The PSO-PID controller controls the Gate pulse of the SEPIC converter. The model is developed in MATLAB/Simulink, the performance of the proposed PSO-PID control is measured in variable input power condition. The hardware model is developed using MSP430 microcontroller to test the efficiency of the PSO-PID controller in the real time environment.

“…The commutation point of the high-speed BLDC is important because of the low inductance causing current spike. Therefore, the performance of the high-speed BLDC motors has been increased by using a novel sensorless drive method [10]. In the satellite power section, the current fluctuation of the BLDC motor is an important problem when mechanic problems occur while it operates in the charge mode.…”

Satellites have a dark region and a bright region in their orbit path. The flywheel energy storage unit is an electric energy provider for a satellite in the dark region. Brushless dc motors (BLDC) are used in the flywheel energy storage unit. The current surge of the BLDC motors is an undesirable situation for solar panels which are used in the satellite motion systems and satellite power systems. Therefore, the current reference method (CRM) is preferred in these systems. The setting of the controller parameters (proportional (P), integral (I) and derivative (D)) is an important problem for the control of the BLDC motor current. Optimum performance cannot be obtained by the calculation of PID parameters using conventional methods. In recent years, hybrid genetic algorithms (GA) are used in the solution of complex problems. In this study, a CRM method was proposed to protect the satellite power system and solar panels. The defined block diagram for the CRM method was used to control the current of the BLDC. In order to calculate conventional method and hybrid GA-based method, the performance of the PID controllers was compared by using MATLAB/SimPowerSystem blocks.

The method of sensorless control of switching of windings of three-section BLDC motor with permanent magnets based on calculation of back-EMF of rotation is proposed. After converting the equations of the three-section BLDC motor to a two-phase system, the switching moments of the windings are determined. Switching moments are calculated using a function representing the ratio of back-EMF rotations computed for a two-phase system. In these moments back-EMF of the turned off and turned on sections are equal. Using this function, signals are generated to control the transistors of inverter. We consider a BLDC motor with a trapezoidal back-EMF of rotation, which is approximated by a piecewise linear function and an inscribed ellipse. Modeling of three-section BLDC using the proposed method of sensorless control of switching windings confirmed the effectiveness of the method and the possibility of its use in a wide range of rotor speeds.
