“…The extended back-EMF estimation method, however, cannot effectively determine the rotor position at low-speed. The second method uses a high-frequency injection voltage to produce its related high-frequency currents [10][11][12][13][14][15]. The high-frequency injection method, however, requires some extra hardware or software to implement a high-frequency generator and also produces audible noise and electromagnetic interference [10][11][12][13][14][15].…”

This paper investigates the implementation of a wide-adjustable sensorless interior permanent magnet synchronous motor drive based on current deviation detection under space-vector modulation. A hybrid method that includes a zero voltage vector current deviation and an active voltage vector current deviation under space-vector pulse-width modulation is proposed to determine the rotor position. In addition, the linear transition algorithm between the two current deviation methods is investigated to obtain smooth speed responses at various operational ranges, including at a standstill and at different operating speeds, from 0 to 3000 rpm. A predictive speed-loop controller is proposed to improve the transient, load disturbance, and tracking responses for the sensorless interior permanent magnet synchronous motor (IPMSM) drive system. The computations of the position estimator and control algorithms are implemented by using a digital signal processor (DSP), TMS-320F-2808. Several experimental results are provided to validate the theoretical analysis.

“…On the contrary, the authors in [25][26][27][28][29][30][31][32] use mainly magnetically linear models of PMSMs for similar purposes. Different methods that can be used to determine the parameters of magnetically nonlinear PMSM and SRM models are presented in [11,12], [16], [19][20][21] and [33][34][35][36][37][38][39][40].…”

His research interests include electrical machines and devices, power quality, and power-system protection and control. Boštjan Polajžer is the head of the Power Engineering Institute at the Faculty of Electrical Engineering and Computer Science, University of Maribor.vii Preface to "Energy Efficiency in Electric Devices, Machines and Drives"Energy efficiency is one of the issues that cannot be avoided when dealing with electrical devices, machines, drives, and systems. Products that do not achieve the minimum efficiency levels specified in standards cannot be sold and every increase in energy efficiency reduces energy consumption and thus the cost of energy supply. Improvements in energy efficiency on a global scale reduce the energy demand and increase the energy supply, which indirectly reduces greenhouse gas emissions.The key element in improving the energy efficiency of electrical devices, machines, and drives is the reduction of losses, which can be achieved using various methods. The development of new materials seems to be the most challenging. New solutions in design, design improvements, and optimization can contribute significantly to improving energy efficiency. When an electrical device or machine is manufactured, further improvements in energy efficiency can be achieved by an appropriate selection and matching of power electronic components with the inherited characteristics of machines or devices. Proper control of systems consisting of electrical devices or machines, and power electronics components based on advanced system models can further improve the overall energy efficiency of systems. When electric devices, machines, and drives operate within a system, a properly implemented energy management system, based on in-depth knowledge of the technological process, can improve energy efficiency at the system level. Some cases of the aforementioned approaches to improving energy efficiency are discussed in this Special Issue.

“…Saturation and cross-saturation effects and self-sensing control strategies have been investigated in depth for interior permanent magnet synchronous machines (IPMSMs). In [9][10] [11] [12] inductance ellipse variation under load condition is analyzed for IPMSMs. Orientation and eccentricity of the inductance ellipse have been shown to vary depending on the dq-axes current level; the orientation of the ellipse has been shown to depend on the cross saturation, while the eccentricity of the ellipse has been shown to depend on the inductive saliency between d-and q-axes.…”

“…In [11] [12], HF is injected in tilted phase angle to improve the self-sensing performance of an IPMSM while operating the machine near the maximum torque per ampere (MTPA) trajectory. In [9][10] [11] [12], additional efforts based on offline characterization of saturation and crosssaturation have been made to enhance the self-sensing performance of PMSMs.…”
