Internal Model Control (IMC) design procedure is known to offer valuable advantages over classical control methods, especially for robust controller design. The Perfect Controller is defined using the well-known classical PID algorithm and its equivalence to IMC. After the definition of the Perfect Controller the IMC filter tuning parameter, which is used to maintain robustness, is obtained as a result of reparametrization of the classical PID control algorithm and factorization of the model. Through factorization, invertible part of the model is used directly in defining the perfect controller and the noninvertibility effects of the model are lumped into the new IMC tuning parameter. Closed loop IMC controller design is obtained with appropriate plant parameter uncertainty representation. Theoretical foundation for the transition from classical PID design to IMC design is analyzed using simple common chemical process models.

Model Predictive control(MPC)performance for controlling reaction systems Aşar, Işık; Özgen, Canan; Department of Chemical Engineering (2004) In this study, the performance of the Model Predictive Controller (MPC) algorithm is investigated in two different reaction systems. The first case is a saponification reaction system where ethyl acetate reacts with sodium hydroxide to produce sodium acetate and ethanol in a CSTR. In the reactor, temperature and sodium acetate concentration are controlled by manipulating the flow rates of ethyl acetate and cooling water. The model of the reactor is developed considering first principal models. The experimen...
Mathematical modeling of gate control theory Agi, Egemen; Özgen, Canan; Department of Chemical Engineering (2009) The purpose of this thesis work is to model the gate control theory, which explains the modulation of pain signals, with a motivation of finding new possible targets for pain treatment and to find novel control algorithms that can be used in engineering practice. The difference of the current study from the previous modeling trials is that morphologies of neurons that constitute gate control system are also included in the model by which structure-function relationship can be observed. Model of an excitable...
Optimum design of pın-jointed 3-D dome structures using global optimization techniques Saraç, Yavuz; Hasançebi, Oğuzhan; Department of Civil Engineering (2005) Difficult gradient calculations, converging to a local optimum without exploring the design space adequately, too much dependency on the starting solution, lacking capabilities to treat discrete and mixed design variables are the main drawbacks of conventional optimization techniques. So evolutionary optimization methods received significant interest amongst researchers in the optimization area. Genetic algorithms (GAs) and simulated annealing (SA) are the main representatives of evolutionary optimization m...
Numerical simulation of laminar reaction flows Tarhan, Tanıl; Selçuk, Nevin; Department of Chemical Engineering (2004) Novel sequential and parallel computational fluid dynamic (CFD) codes based on method of lines (MOL) approach were developed for the numerical simulation of multi-component reacting flows using detailed transport and thermodynamic models. Both codes were applied to the prediction of a confined axisymmetric laminar co-flowing methane-air diffusion flame for which experimental data were available in the literature. Flame-sheet model for infinite-rate chemistry and one-, two-, and five- and ten-step reduced fi...
Development of a Design Methodology Against Fast Cook-Off Threat for Insensitive Munitions ŞAHİN, Hakan; NARİN, Bekir; Kurtuluş, Dilek Funda (Wiley, 2016-06-01) This work provides a design methodology for a typical energetic system to get Type V insensitive munition (IM) response against fast cook-off threat. Experimental and numerical results for a generic test item filled with PBXN-109 explosive are presented. Two key aspects of IM design against fast cook-off threat are investigated, which are "time-to-reaction" and "critical ventilation area". By dividing the problem to pre-ignition and post-ignition, the complexity of the problem is reduced. The first part of ...
