Abstract :
In this paper genetic algorithms are applied as an optimization strategy in a controller order reduction procedure. GAs capability to get out local minima is used to determine a reduced-order controller which optimally approximate the full-order one. Particular attention has been devoted to guarantee a good stability margin and a suitable index is minimized, by using GAs, in order to compute the parameters of a reduced-order controller which guarantee the stability of the closed loop systems. An example taken from literature has been reported to confirm the suitability of the strategy
