Thiết kế các bộ điều khiển logic mờ sugeno kiểu PID để điều khiển tốc độ máy phát điện trong nhà máy thủy điện

Abstract

Fuzzy logic -based control strategies have been considered to be a feasible replacement of conventional PID regulators due to their dominant advantages. One of the most outstanding characteristics of a fuzzy logic -based control scheme is that the system might not require full parameters as well as an exact model; instead, it depends only upon experts' understanding about the control plant. This paper proposes the design of a novel PID -like Sugeno -based fuzzy logic controller. With a significant set of fuzzy rules and four scaling factors tuned by a proper optimization method, such a Sugeno -based inference model is completely able to solve a lot of complicated control problems. A typical control issue concerning the speed stability of generators in hydropower plants applying the studied fuzzy logic controllers will also be taken into consideration. Promising simulation results obtained demonstrate effectiveness and applicability of the control methodology proposed in this study.
