Design of decentralized robust controllers for multizone space heating systems

Honey bee social foraging algorithms for resource allocation: Theory and application

“…Achievement of high performance multizone temperature control is very important in a range of commercial and industrial applications. For instance, recent work in this area includes distributed control of thermal processes (Jones et al, 2003;Zaheer-uddin et al, 1993;Emami-Naeini et al, 2003;Demetriou et al, 2003;Ross, 2004), and semiconductor processing (Alaeddine and Doumanidis, 2004a, b;Schaper et al, 1999b). Particularly relevant to our work is the study in EmamiNaeini et al (2003), where the authors use multivariable distributed control in order to maintain a uniform temperature across a wafer during ramp-up (similar to the control objective we study here).…”

The Ideal Free Distribution: Theory and Engineering Application

“…It has been proven that V is a valid Lyapunov function candidate (e.g., see [15]). The derivative of V along the trajectories in (18)…”

“…Others [17] study distributed control of wafer temperature via multizone rapid thermal processing systems. In related work, the authors of [18] describe a multizone space heating system that maintains a desired temperature in different zones. Another application where the type of multizone temperature control that we study is very important is in personal computers.…”

Robust decentralized control of HVAC systems using -performance measures

“…To achieve this regulation task, we can use (i) the station 1 input u 1 ðtÞð¼ n 3 Þ to control the output y 1 ðtÞ; (ii) the station 2 input u 2 ðtÞð¼ ½n 1 n 4 T Þ to control the output y 2 ðtÞ, and (iii) the station3 input u 3 ðtÞð¼ ½n 2 n 5 T Þ to control the output y 3 ðtÞ. In a recent paper by Zaheer-uddin et al [1], a robust decentralized controller was designed for the HVAC system by using a parameter optimization technique to solve a constrained servomechanism problem.…”

“…In this paper, we seek to answer systematically whether H 1 performance measures improve the regulation properties of an HVAC control system, and if so what improvements can be achieved. Furthermore, we are interested in the application of H 1 controller design techniques in the frame work of decentralized control since in a previous study by Zaheer-uddin et al [1], we have shown that decentralized controllers are good candidates for HVAC systems. To this end, we begin with the HVAC system shown in Fig.…”
