Transient response analysis of a fuzzy logic controller
G. Abdelnour, John Y. Cheung · 2003
The exponential-input describing function technique is utilized to investigate the transient response of a fuzzy controller. The symmetric features that fuzzy addition introduces in the decision table of a fuzzy control algorithm made possible the decoupling of the effects of the output error time sequences and, consequently, the representation of the algorithm by multilevel relays. Computer simulations were carried out on a second-order system to assess the performance of the controller, and determine the accuracy of the approximate solution.>
