The document discusses developing a fuzzy PI(D) controller for a dynamic system with first order dynamics and delay. A fuzzy logic controller (FLC) with two inputs - error (e(k)) and change in error (Δe(k)) - and one output is created using triangular membership functions. The FLC is implemented in Simulink along with other blocks like filters and a multiplexer to control the dynamic system and reduce steady state error to zero, with the integral part of the controller driving error to zero over time. The performance of the fuzzy controller is then evaluated through simulation.
