Abstract:
This paper presents the designing of fuzzy logic controller for a twin rotor multi-input-multioutput
system (TRMS). The control objective is to make the beam of the TRMS move
quickly and accurately to the desired positions, i.e., the pitch and the travel angles.
Developing controller for this type of system is challenging due to the coupling effects
between two axes and also due to its highly nonlinear characteristics. In this investigation
accurate dynamic models of the system for both vertical and horizontal movements are
developed so as to get very similar responses to that of the real plant. These models are
then used as test-beds to develop a set of fuzzy controllers. The performance of the
controllers in tracking movements in both vertical and horizontal planes is found to be very
satisfactory. A comparative performance study of this fuzzy control approach with respect
to a single PID approach is also presented in this study
