In this paper, we present the design of a Proportional Integral (PI) controller using Genetic Algorithm (GA) to control the speed of an induction motor (IM). The GA methods have been employed successfully to solve complex optimization problems. The main advantage of this metaheuristic method (GA) is its simplicity and robustness. Only speed error is(More)
In this paper, blind image separation is performed, exploiting the property of sparseness to represent images. A new sparse representation called forward difference method is proposed. It is known that most of the independent component analysis (ICA) basis functions, extracted from images are sparse and gives unreliable sparseness measure. In the proposed(More)
