Applications of Computational Verbs to the Design of P-Controllers

The design of P-controllers based on computational verb theory is to generalize fuzzy P-controllers from using fuzzy sets to using computational verbs. As a part of fuzzy PID controller, a (digital) fuzzy P-controller is designed based on the fuzzification of error signals and their first differences. To generalize a fuzzy P-controller into a verb P-controller, first the fuzzy control rules are mapped onto a phase plot. Then based on the spatial dynamics of control errors shown in the phase plot, verb control rules are constructed. Detailed design examples and simulation results are used to demonstrate the design process. Copyright c © 2004-2005 Yang’s Scientific Research Institute, LLC. All rights reserved.
