“…Indeed, GAs, Multi-Objective GAs and Particle Swarm Optimization (PSO) are the most encountered algorithms.

To remain competitive, the manufacturing industry is using computer processing power to innovate, develop and optimize new cost-efficient production strategies. This is the reason why optimization of automation systems is deployed to improve productivity, quality and robustness of the production. The different existing goals of optimization as the control machine, management of the power consumption, design of electrical installation and prediction of motor faults lead to the necessity of estimating the induction machine parameters (the stator and rotor resistances, the stator and rotor inductances and the magnetizing inductance). To these ends, researchers and companies are investigating efficient methods to identify these parameters. In this paper, we propose an effective method for the induction machine parameters identification based on the new -NSGA III genetic algorithm. A comparison between a classic single objective genetic algorithm (GA) and two well-known multiobjectives GAs (NSGA II and -NSGA III) is performed. Our results show that the multi-objective GA -NSGA III provides a better estimation of parameters than the classic single objective GA and the multi-objective GA NSGA II.

In this study a wound rotor AC induction machine which can be used in wind turbine is modeled in LabVIEW program and the system model optimization is done with system identification (SI) method. Wind turbines are usually used as synchronous and asynchronous. In this study, to be safe and because of the advantages such as low costs, WRIM is preferred. In the control of the excitation circuit, SI method is used to provide more safe, effective and efficient control. With this method, control parameters are optimized to be used on the system. In simulations real wind data are used as input to approach reality.
“…Since the fluxes on α and β axes are difficult to determine theoretically based on voltage and current in real-time applications, artificial neural networks [1], genetic algorithm (GA) [2][3][4][5], or particle swarm optimization (PSO) [6][7][8] and algorithm comparison (GA-PSO, GA-modified GA, PSO-modified PSO, GA-cuckoo alg., etc.) [9][10][11][12][13][14] can be used. Heuristic algorithms afford relatively easy numeric solutions for problems difficult to be solved theoretically.…”
Abstract:The estimations of induction machine equivalent circuit parameters are still being widely used in the analysis and in determining the characteristics of the machine. Since the most important part of the machine is the rotor where torque is produced, the calculation of rotor resistance correctly will directly affect all other data. Almost all parameters belonging to the stator side can easily be determined through external measurements. However, due to the formulation of the rotor as a closed box, estimating rotor resistance and the rotor's slot shape by heuristic algorithms, without damaging the rotor physically, and comparing it with its actual value constitutes the first focus of this study. In this regard, rotor resistance and slot parameters are estimated through heuristic algorithms depending on the induction machine design aspects. Secondly, an improved particle swarm optimization is presented and compared with conventional PSO and genetic algorithm.
