Optimal Control Using Evolutionary Algorithms Mînzu, Viorel Optimal Control Problems involve dynamic systems that are subject to algebraic or differential constraints and whose evolution may be characterized by a performance index. Such a problem can be solved by the well known Evolutionary Algorithms. This paper proposes an evolutionary algorithm having usual characteristics concerning the mutation and crossover operators. Generally speaking, the EA gave good results and the convergence was acceptable. But for a specific problem instance, the evolutionary algorithm underperformed on the first simulation series. Therefore, the paper proposes a new mutation operator having adaptive Gaussian standard deviation of genes' values variation.

Real-Time Optimal Control Using Particule Swarm Optimization Mînzu, Viorel Optimal Control Problems can be solved by a well known metaheuristic, Particle Swarm Optimization. A version of this metaheuristic has been used to develop an algorithm that solves such a problem. The solution can be used to control the considered dynamic system only in open loop. Therefore, the main problem is how to use the PSO algorithm in a control structure that works in closed loop. The solution of this problem is to use the well known control structure Model Predictive Control whose controller has an optimization algorithm that minimizes the prediction error. The proposal of this work is to confer this role to the PSO based algorithm because it would minimize implicitly the prediction error.
