A Justification for the Wider Use of Fuzzy Logic Control Algorithms

An investigation is described that attempts to demonstrate the benefits that can be gained by wider application of fuzzy logic control. The views presented are based on the control of a flexible communications satellite. Regions are identified in which the fuzzy logic controller's performance is superior to that of a classical design, when process mismatch is significant. Employing an approach incorporating Lyapunov's second method a parameter space is located where controller coefficients can be selected with relative confidence.
