“…Motor drives are equipment based on power electronics, used to control the rotation speed and the torque of the electric machines. Motor drives can be found in several industrial applications (e.g., pumps, fans, conveyor belts), as well as in domestic appliances (e.g., washing machines, fans, air conditioning) for different machine types (e.g., PMSM drives [336], induction motor drives [337], and BLDC drives [338]).…”

Nowadays, new challenges arise relating to the compensation of power quality problems, where the introduction of innovative solutions based on power electronics is of paramount importance. The evolution from conventional electrical power grids to smart grids requires the use of a large number of power electronics converters, indispensable for the integration of key technologies, such as renewable energies, electric mobility and energy storage systems, which adds importance to power quality issues. Addressing these topics, this paper presents an extensive review on power electronics technologies applied to power quality improvement, highlighting, and explaining the main phenomena associated with the occurrence of power quality problems in smart grids, their cause and effects for different activity sectors, and the main power electronics topologies for each technological solution. More specifically, the paper presents a review and classification of the main power quality problems and the respective context with the standards, a review of power quality problems related to the power production from renewables, the contextualization with solid-state transformers, electric mobility and electrical railway systems, a review of power electronics solutions to compensate the main power quality problems, as well as power electronics solutions to guarantee high levels of power quality. Relevant experimental results and exemplificative developed power electronics prototypes are also presented throughout the paper.

“…Therefore, in IPM motor control technologies, maximum torque per ampere (MTPA) control methods are often used to improve the efficiency of IPM motors and provide maximum torque or minimum stator current to minimize copper losses. Based on the field oriented control (FOC) technology and the equivalent model of IPM motor in the direct-quadrature (dq) frame, the conventional offline method for implementing MTPA control is to calculate MTPA equations, under the assumption of stable and known motor parameters [5], [6]. However, due to steel saturation, crosssaturation and flux linkage affected by temperature, motor parameters vary depending on different operating conditions.…”

In commercial electrical equipment, interior permanent magnet (IPM) synchronous motors undergo variations in temperature and parameters under different operating conditions. Conventional maximum torque per ampere (MTPA) control using fixed parameters lacks accurate motor parameter information, which can negatively impact the operating efficiency of electrical equipment. To address the above problem, this paper proposes a simple online MTPA control method without motor parameters. To approximate the interface structure of the conventional MTPA controller, a back propagation neural network (BP-NN) adjuster with a space vector decomposer is designed as the MTPA controller. Moreover, by leveraging the similarity between the loss function of the BP-NN and the stator current representing the efficiency of the IPM motor, the teacher signal is cleverly chosen to update the parameters of the BP-NN online. In the discrete domain, the motion mechanism of the proposed method is analyzed and characterized by the perturb & observe technique. Compared to the conventional MTPA control using fixed parameters, the feasibility and high efficiency of the proposed method for copper-loss-minimization control were validated in the simulation. The feasibility of the proposed method was further validated in simulated scenarios involving sudden changes in torque and speed. Furthermore, the transient characteristics of the output stator current were analyzed. Overall, the proposed method can achieve true online MTPA control without motor parameters.INDEX TERMS interior permanent magnet synchronous motor, field oriented control, maximum torque per ampere control, back propagation neural network, loss function, perturb and observe.

“…The conventional approach to this problem is the calculation of MTPA equations obtained from the motor model by differentiating the motor torque equation with respect to the stator current. These MTPA equations are analytical solutions for this problem, which are frequently obtained under the assumption that motor parameters are stable and do not depend on other variables [21,22]. However, motor parameters variate depending on the operating conditions and the most significant changes are in inductances, because of the steel saturation; cross saturation, and flux linkage, which is affected by temperature.…”

This paper discusses the Maximum Torque Per Ampere (MTPA) control of synchronous motors, which have become an indispensable part of highly-efficient motor drives. It explains the nature of torque produced by synchronous motors, ways to find its maximum and algorithms to operate at this point, despite changes of loads and motor parameter variations. The authors propose a classification of the MTPA methods, based on the features of each algorithm or group of similar methods. They demonstrate the conventional control scheme and discuss the modifications necessary for the implementation of each method. This paper reviews existing maximum torque per ampere control algorithms, discusses their pros and cons and suggests possible areas of usage for each group of methods. The authors of the paper share their vast experience in the industry and research aspects, which were obtained by developing industrial, commercial, traction and military drives, and report on their views on the perspective of each method taken into consideration.
