“…T HE USE of a genetic algorithm (GA) requires the choice of a set of genetic operations between many possibilities [1]. For example, the crossover operation with two cut points, mutation bit by bit, and selection based on the roulette well.…”

This paper presents an exhaustive study of the Simple Genetic Algorithm (SGA), Steady State Genetic Algorithm (SSGA) and Replacement Genetic Algorithm (RGA). The performance of each method is analyzed in relation to several operators types of crossover, selection and mutation, as well as in relation to the probabilities of crossover and mutation with and without dynamic change of its values during the optimization process. In addition, the space reduction of the design variables and global elitism are analyzed. All GAs are effective when used with its best operations and values of parameters. For each GA, both sets of best operation types and parameters are found. The dynamic change of crossover and mutation probabilities, the space reduction and the global elitism during the evolution process show that great improvement can be achieved for all GA types. These GAs are applied to TEAM benchmark problem 22.

“…During the second step (final design) a three dimensional finite element model is used [1] in order to account for both the complicated geometry of the air-gap and iron saturation. This second stage enables a more detailed analysis of the machine and can be used in conjunction with a minimizing procedure in order to optimize the claw geometry in the specific application [2][3][4].…”

The paper presents a procedure for the design of claw pole alternators for small scale wind power applications. The method involves a preliminary design stage by means of the classical magnetic circuit analysis and a detailed design stage involving a 3D finite element model. This technique has been implemented in the design of a multiple generation for a small scale gearless autonomous system. The developed model can be implemented for the optimization of the rotor claw geometry through a minimization algorithm.

“…However, the optimization of the rotor geometry may require laborious and expensive numerical schemes especially when 3D configuration should be considered [4,5]. Although both stochastic [6] and deterministic optimization algorithms can be implemented [7][8][9], the sensitivity analysis technique combined with finite element methods enables robust and fast convergence [1].…”
