M. Mahfouf et al., Multi-objective genetic optimisation of GPC and SOFLC tuning parameters using a fuzzy-based ranking method, IEE P-CONTR, 147(3), 2000, pp. 344-354
A multi-objective genetic algorithm is developed for optimising the tuning
parameters relating to the generalised predictive control (GPC) and perform
ance index table of the self-organising fuzzy logic (SOFLC) algorithms, usi
ng a multi-objective ranking method based on fuzzy logic theory. A comparat
ive study with more traditional pareto, average and minimum distance rankin
g methods shows that the proposed method is superior. The study shows that
the approach leads to a more effective set of tuning parameters, especially
those relating to the important observer polynomial for GPC and to a good
reference trajectory for SOFLC. Up to two objective functions were used in
the study, although the method can be extended to more objectives. A nonlin
ear muscle-relaxant anaesthesia model is used as a case study to demonstrat
e the robustness of the method.
