Fuzzy logic control for watering system
Scientific Reports, 2023 AbstractA two-dimensional finite element (FEM) model was developed to simulate water propagation in soil during irrigation. The first dimension was water distribution depth in soil, and the second dimension was time. The developed model was tested by analyzing water distribution in a conventional (clock-controlled) irrigation model.

Fuzzy PID Control for Respiratory Systems [PDF]
Journal of Healthcare Engineering, 2021 This paper presents the implementation of a fuzzy proportional integral derivative (FPID) control design to track the airway pressure during the mechanical ventilation process. A respiratory system is modeled as a combination of a blower-hose-patient system and a single compartmental lung system with nonlinear lung compliance.

Perspectives of fuzzy systems and control [PDF]
Fuzzy Sets and Systems, 2005 Although fuzzy control was initially introduced as a model-free control design method based on the knowledge of a human operator, current research is almost exclusively devoted to model-based fuzzy control methods that can guarantee stability and robustness of the closed-loop system.

FUZZY CONTROL FOR MULTIVARIABLE SYSTEMS
IFAC Proceedings Volumes, 1983 Abstract In this paper a fuzzy control algorithm for regulator control of multivariable systems based on a state space model of the system is introduced. Its application to several linear systems is illustrated and compared with systems controlled by means of linear feedback laws as obtained via an INA-design or linear output feedback.

Controlled Fuzzy Parallel Rewriting [PDF]
, 1996 We study a Lindenmayer-like parallel rewriting system to model the growth of filaments (arrays of cells) in which developmental errors may occur. In essence this model is the fuzzy analogue of the derivation-controlled iteration grammar.

Observability and Decentralized Control of Fuzzy Discrete Event Systems [PDF]
, 2005 Fuzzy discrete event systems as a generalization of (crisp) discrete event systems have been introduced in order that it is possible to effectively represent uncertainty, imprecision, and vagueness arising from the dynamic of systems.

A new approach to adaptive fuzzy control: the controller output error method [PDF]
, 2002 The controller output error method (COEM) is introduced and applied to the design of adaptive fuzzy control systems. The method employs a gradient descent algorithm to minimize a cost function which is based on the error at the controller output.
