In this paper, optimal control problems for switched systems are studied. In particular, we focus on such problems given a prespecified sequence of active subsystems and propose two approaches based on meta-heuristics to find the optimal switching instants. The first one is based on the Genetic Algorithm (GA) and the second on the Particle Swarm(More)
In this paper, optimal control problems for switched discrete systems are studied and compared to the same optimal problem for a continuous system; in particular we focus on problems in which a prespecified sequence of active subsystems is given and propose a metaheuristic approach to find the optimal switching instants. This approach is based on Particle(More)
In this paper, we studied the optimal control problems for switched non linear systems; in particular we focus on problems in which a prespecified sequence of active subsystems is given and propose a discrete Particle Swarm Optimization approach to find the optimal switching instants. The objective is to minimize the performance criterion wish depend on(More)
Our work focuses mainly on the optimal control issues for switched nonlinear systems. In fact, we are interested, especially, in studying some cases in which we obtain a pre-specified string of active subsystems. Besides, we suggest Genetic Algorithm approach in order to obtain the optimal switching instants. We intend mainly to reduce the cost function(More)
