Evolutionary achievement of diagonal dominance in linear multivariable plants

摘要

Adaptive evolution strategies without crossover are used to design precompensators for linear multivariable plants. Such compensators are required to achieve diagonal-dominant plant transfer function matrices in order to reduce plant interactions as much as possible. The effectiveness of the evolutionary design technique is illustrated by synthesising a multivariable pre-compensator for the Rolls-Royce Spey jet engine.
