Description

Designing a linear controller that performance satisfactorily within a non-linear operating envelope is a difficult control engineering problem. In this paper, a new adaptative particle swarm optimisation algorithm is proposed, that can track difficult dynamic search landscapes. the proposed adaptive particle swarm algorithm is applied to design linear discrete PI regulators to control a clasical non-linear concentration ssystem, in wich the operating point conditions change considerably with the input flow change. Simulation results are presented that show the effectiveness of the proposed evolutionary based design technique.
