Composite Fuzzy-Based Control Strategy for Uncertain Underactuated System
Most practical systems are influenced by disturbances and uncertainties within their models, increasing the need for robust control algorithms. Type-2 fuzzy theory and its variant, interval type-2 fuzzy, are well-regarded for their capability to ...

A Development of Fuzzy-PID Controller Applied on an Autonomous Surface Vehicle
Precise trajectory tracking remains a significant challenge for Autonomous Surface Vehicles (ASVs) due to their inherent nonlinear and strongly coupled surge-sway-yaw dynamics, which are often exacerbated by environmental disturbances.

Variable Universe Fuzzy Control of Soft-start for Asynchronous Motor
Soft-start system of asynchronous motor is a typical time-varying, non-linear system. The instantaneous impact of the starting current is large, which has a great influence on the motor, the drive equipment and the power grid.

A New Fuzzy PID Control System Based on Fuzzy PID Controller and Fuzzy Control Process
International Journal of Fuzzy Systems, 2020In this paper, we present a fuzzy PID control system as a combination of a fuzzy PID controller and a fuzzy control process, which is represented by a fuzzy control differential equation in linear form. We use the concepts of the generalized Hukuhara differentiability and the fuzzy integral of fuzzy-valued functions to study some qualitative properties

Expert Systems with Applications, 2021
Abstract In this paper an uncertain dynamical system is investigated in which the coefficients are as a class of fuzzy sets and the fuzzy derivative is considered as the granular derivative. Furthermore, the notions of granular second order derivative of a fuzzy function, fuzzy overshoot, fuzzy rise-time, and fuzzy peak-time are introduced.

Stability of fuzzy PID controllers
IEEE Transactions on Systems, Man, and Cybernetics - Part A: Systems and Humans, 1998In this paper, the stability of fuzzy PID controllers is studied. Using the passivity theorem, the stability region of the effective PID parameters can be derived and hence some sufficient conditions for a stable fuzzy controller can be obtained. With these conditions satisfied, a stable set of fuzzy rules can be designed easily.
