Study and Implementation of a Fuzzy PD Thermal Comfort Controller for Embedded Fieldbus Systems Applications
نویسندگان
چکیده
The aim of this paper is to present the design and evaluation process of a Fuzzy PD controller for an experimental platform for buildings based on a fieldbus system. The experimental platform consists of interconnected nodes (sensors and actuators), using the European Installation Bus (EIB) fieldbus network infrastructure. A “smart node” consisted of a personal computer, containing custom control software, is attached to the above installation and executes the control process program. The controlled parameter is the indoor thermal comfort of the installation zone expressed by the Predicted Mean Vote (PMV) function. The software deployed on the “smart node” makes use of the measurements collected from the sensors and gives the appropriate output values to the actuators using various fuzzy logic algorithms. By application of past studies results, a minimal Fuzzy PD thermal comfort controller is implemented and evaluated. This controller is designed taking into account the easiness of future deployment onto embedded systems with limited memory and processing power capabilities. Key-Words: Fuzzy Logic, Embedded Systems, Thermal Comfort, Predicted Mean Vote, Fieldbus Systems

This paper presents H∞ control problem for input-delayed systems. A neutral system approach is considered to the design of PD controller for input delay systems in presence of uncertain time-invariant delay. Using this approach, the resulting closed-loop system turns into a specific time-delay system of neutral type. The significant specification of this neutral system is that its delayed coeff...
