Abstract
ABSTRACT
A new dual fuzzy controller for the nonlinear model of the compression system is
proposed in this paper. The surge phenomenon in the centrifugal compressor, the nonlinearities
and uncertainties of the compression system make it impossible to use a
conventional controller over a wide range of operation. This fuzzy controller is designed
to consist of a active surge control and phase control without any explicit system
models, but driven in the human thinking mechanism. A simulation example of
compression system is given to demonstrate the validity of the proposed control
scheme. It is shown that the fuzzy controller can be simplified, and good tracking
control performance can be achieved by choosing appropriate fuzzy roles. However,
the dual fuzzy controller can successfully intervene in the control surge of the
compression system. This new fuzzy control methodology suggested in this work
reproduced well the main characteristics of the turbo compressor dynamic model
developed by Moore and Gretzer and give place to a more precise and easy to handle
representation. It is about a inaccuracies reproducing with a certain degree of
satisfaction of the real process without being as much complex.
