“…In [34], by simulating a series of linear, incremental permeability, the cage losses in IMS, which are computed due to the harmonic fields considering the fundamental flux saturation, are calculated and a finite element analysis (FEA) procedure is proposed. The transient loss in an induction motor with rotor field-oriented control is studied in paper [35].…”

Squirrel-cage induction motors are increasingly displaying a broken rotor bar fault, which represents both a technical problem and an economic problem. After confirming that the broken rotor bars do not affect the normal start-up and basic working performance of the squirrel-cage induction motor, this paper focuses on the loss and efficiency changes of the motor brought about by the broken rotor bar fault. Using finite element simulation and experimentation, various losses like stator copper loss, iron loss, rotor copper loss, mechanical loss and additional losses, total loss and efficiency are obtained. By combining price and cost factors, the cost-effective measures that can be taken after the occurrence of different degrees of broken bars are evaluated here to provide guidance for correctly handling this problem.

“…An alternative solution based on a filtered flux linkage setpoint in the transient regime was discussed in [18]. In [19,20], polynomial flux linkage prototypes obtained from a numerical solution of the optimization problem were used to reduce losses. In [21], a closed-form solution to the optimization problem based on Pontryagin's principle was proposed.…”

“…In the cited publications addressing dynamic optimization, iron losses were considered in [12,15,19,20,23], whereas in [16,21], only copper losses were considered. In all cited publications, the optimization interval during dynamic operation of the motor started at the beginning of the torque or speed change.…”

Energy efficiency optimization techniques for steady state operation of induction machines are the state-of-the-art, and many methods have already been developed. However, many real-world industrial and electric vehicle applications cannot be considered to be in steady state operation. The focus of this contribution is on the efficiency optimization of induction machines in dynamic operation. Online dynamic operation is challenging due to the computational complexity and the required low sample times in an inverter. An offline optimization is therefore conducted to gain knowledge. Based on this offline optimal solution, a simple and easy to implement template based solution is developed. This approach aims at replicating the solution found by the offline optimization by resembling the shape and anticipative characteristics of the optimal flux trajectory. The energy efficiency improvement of the template based solution is verified by simulations and measurements on a test bench and using a real-world drive cycle scenario. For comparison, a model predictive numerical online optimization is investigated too.

The current paper discusses the adaptive choice of a filter time constant for filtering the steady-state flux reference in the energy-efficient control problem of field-orientation induction machines in transient behavior when load and speed conditions are changing taking into account the effect of the main induction saturation. It is shown that by appropriately managing the flux linkage rate of change the energy losses per full operation cycle under torque changes can be significantly reduced compared to the conventional cases. The analysis for the appropriate choice of the filter time constant as a fraction of the rotor time constant is based on a numerical study and simulation results for three different induction machines with different rated powers.Statement of the problem and analysis of the recent research and publications. The induction machine is widely used in industrial applications due to its robustness and its low cost compared to permanent magnet synchronous machines. However, in part-load operation, the efficiency of the induction machine dramatically decreases when the flux is kept at the nominal level. To address this issue different strategies have been developed in the past to increase the efficiency of the induction machine in a large operation range [1], [2]. However, when the induction machine is operated under changing loads these methods will not yield maximum efficiency. A solution to this problem in the framework of vehicle applications is given in [3]. However, the motor for these applications will often operate in dynamics with changing torques and speed up to voltage and current limits. The development of parametrized prototypes is discussed in [4]. Unfortunately, without voltage and current limits as well. These limits require the knowledge of the behavior of the process quantities, which can be obtained from offline optimization [5]. �� Diachenko G.G., Aziukovskyi O.O., 2020� «Системні технології» 5 (130) 2020 «System technologies» ISSN 1562-9945 (Print) ISSN 2707-7977 (Online)
