A Genetic Algorithm Compared with a Gradient-Based Method for the Solution of an Active-Control Model Problem
Résumé
In this study, a linear active-control model problem is employed to conduct a preliminary performance comparison between a genetic algorithm and a classical optimization method based on the evaluation of a gradient of functional. For this purpose, we consider a system modeled by the heat equation in one space dimension controled by a source term. The cost functional is a quadratic form of the distance between the final state and a prescribed function augmented of a penalty involving the control quadratically. The problem is first solved by a direct identification of the «optimal-control law» from the solution of a Riccati system. A simple genetic algorithm is implemented afterwards and compared.
