Abstract:

Two self-organising controller networks are presented in this study.
The ""Clustered Controller Network'' (CCN) uses a spatial clustering
approach to select the controllers at each instant. In the other gated
controller network, the ""Models-Controller Network'' (MCN), it is the
performance of the model attached to each controller which is used to
achieve the controller selection. An algorithm to automaticly
conctrust the architecture of both networks is described. It makes the
two schemes self-organising.

Different examples of control of non-linear systems are considered in
order to illustrate the behaviour of the ICCN and the IMCN. It makes
clear that both these schemes are performing much better than a single
adaptive controller. The two main advantages of the ICCN over the
IMCN concern the possibilities to use any controller as a building
block of its network architecture and to apply the ICCN for modelling
purpose. However the ICCN appears to have serious problems to cope
with non-linear systems having more than a single variable implying a
non-linear behaviour. The IMCN does not suffer from this trouble.
This high sensitivity to the clustering space order is the main
drawback limiting the use of the ICCN and therefore makes the IMCN a
much more suitable approach to control a wide range of non-linear
systems. 

Regards,

Eric Ronco
