“…By using observer based control, it was also possible to obtain reliable control results. Also, a variety of novel current control methods for sensorless control were introduced [10]- [12]. In addition, new sensorless control methods for actual industrial applications were developed [13], [14].…”

To control sensorless type Brushless DC (BLDC) motors, various back Electromotive Force (EMF) detecting methods have been widely used. In this research, a Finite Elements Method (FEM) model of an 8 pole 12 slot BLDC motor and two kinds of phase-voltage sensing back EMF detecting electrical circuits are coupled to achieve improved and more reliable analysis results. Through this coupled analysis, it becomes possible to analyze the characteristics of the motor and how the electrical circuit affects the motor at the same time. This makes it possible to design high performance embedded motor controllers in the future. An experimental evaluation of the coupled analysis results was also implemented to verify the coupled analysis.

“…Although these methods are open-loop control strategies with easy implementation, they are sensitive to load/motor parameters. Starting methods for BLDC motors under scalar control are proposed in [11] and [12]. These methods synchronize the commutation instants of the inverter with the disturbance that is caused by the back-EMF on the current or on the current loop control action, but they are unsuitable for vector control.…”

This paper proposes an I-f starting method for smooth and fast transition from open- loop frequency control to sensorless field oriented control (FOC) of BLDC motors. The method is divided in three stages: (i) initially the rotor is aligned with a desired angular position; (ii) then, the stator currents are controlled in an arbitrary reference frame to impose the angular frequency of the rotating magnetic field with a suitable profile; (iii) finally, a smooth transition between the arbitrary and the rotor reference frames is accomplished by recalculating the current controller states and references. The proposed method preserves the electromagnetic torque magnitude during the transition avoiding undesired transients. In addition, a procedure based on mechanical model is described to determine a suitable ramp profile. Moreover, the estimated rotor position that is required for FOC as well as for the proposed method is computed by using the estimated back-EMFs from a Luenberger observer. The good performance and robustness under no-load and full load conditions of the proposed starting method are demonstrated by simulation and experimental results.
