Abstract :
Adaptive evolution strategies without crossover are used to design complete dominance-based controllers for linear multivariable plants. Such complete dominance-based controllers comprise a pre-compensator and a set of single-loop controllers, which can both be readily designed using the proposed evolutionary approach. The effectiveness of this two-stage evolutionary design technique is illustrated by synthesising a complete dominance-based multivariable controller for the RollsRoyce Spey jet engine. The performance of this controller is compared with that of a multivariable controller for the Spey engine designed using a one-stage evolutionary design technique, which does not involve the prior achievement of diagonal dominance.
