This paper presents a way that fuzzy logic can be used in high level control functions. Specifically, we examine the use of fuzzy logic in supervisory control, for selecting discrete control actions, identifying the operating environment and evaluating controller performance
POSITION CONTROL FOR (PPDCV) USING PID FUZZY SUPERVISORY CONTROLLER
ABSTRACT Pilot Proportional Directional Control Valve (PPDCV) is mostly used for control the Cement Industries. Accuracy and precision without any disturbance for position control of the actuator is the goal for engineering applications. This paper presents explain
Design of an Elevator Group Supervisory Controller using Ordinal Structure Fuzzy Logic with Context Adaptation
An elevator group supervisory controller is a control system that manages systematically two or more elevators in order to serve passengers as required. The elevator cars are assigned accordingly in response to hall calls, so as to optimize waiting time, riding time, power
Adaptive Fuzzy Logic Controller for Supervisory Power System Stabilizers of a Two-Machine System
This paper presents powerful supervisory power system stabilizers (PSS) using adaptive fuzzy logic controller driven by an adaptive fuzzy (AFS). The system under study is compromised from a two synchronous generators system connect via double transmission
Supervisory Controller for PV and Storage Microgrids
The US Department of Defense has ambitious goals to increase renewable penetration in army installations. Microgrids can achieve this goal, and offer higher energy security, lower operating costs, and maximized renewable use. They can also enable a controllable
Supervisory Fuzzy Controller for Thickener Underflow Solids Concentration on a Simulated Platform
ABSTRACT A thickening process produces continuously a high-density slurry on its underflow, and water free of solids on its overflow. This process is highly non-linear and it is subject to random disturbances from previous process on its operations, consequently its
A TOOL FOR THE DESIGN AND VERIFICATION OF A SUPERVISORY CONTROLLER FOR DISTRIBUTED MANUFACTURING PROCESS
The present paper proposes a tool for the design and verification of a supervisory controller for distributed manufacturing process using UML and Petri nets. UML use cases and class diagrams are used to model the manufacturing process, to be transformed later into their
Modeling and verification of a stepper motor supervisory controller
This master thesis has been carried out at Volvo Technology (VTEC) in Gothenburg during the winter of 2007 and the spring of 2008. In cars with electronic climate control the air flaps are controlled by a couple of intelligent step motors or flap actuator modules (FAM). The
