V. RESEARCH SUMMARY

 

My research goal is to make ground-breaking contributions in control theory, algorithm development, and industrial practice. Towards this end, I strive to select problems that are both theoretically challenging and industrially important. The key fundamental issues associated with a particular control problem of industrial importance are identified, and then the problem is attacked with a high level of mathematical rigor. This statement summarizes the main research accomplishments in the last two years.

 

A. Identification and Control of Sheet and Film Processes.  A significant proportion of U.S. manufacturing is associated with sheet and film processes, which include papermaking, adhesive coating, polymer film extrusion, and sheet metal rolling. The control of these processes is challenging due to high dimensionality, limitations in the quality and quantity of data, and uncertainties in the process interactions and dynamics. I published a book on the identification and control of sheet and film processes [Book2]. The book identifies the root cause of control-induced wrinkling and breaks in papermaking and polymer film extrusion, which was a long-standing question of high importance in those industries. The book describes the first framework for quantifying model uncertainties and optimally designing experiments that is applicable to large scale systems. An algorithm is proposed that enables robust controller design for large scale systems by exploiting model structure. The application to a simulated paper machine, whose model and uncertainty description was constructed from input-output data from an industrial paper machine, was the largest dimension robust controller design problem ever solved [36]. The book also describes a model predictive control algorithm that has on-line computational requirements low enough for real-time application to large scale systems. A U.S. patent based on this algorithm was awarded [Patent1]. Much of these results are summarized in a survey paper [41]. Currently we are setting up a blown film extruder in our laboratory to test and improve our algorithms.

 

B. Fault Detection and Diagnosis.  The early detection of changes in disturbance characteristics, equipment degradation, actuator and sensor failures, and other abnormal operating conditions is necessary for maintaining satisfactory control. The dominant process monitoring algorithms in the chemical process industries are dimensionality reduction algorithms that are able to extract fault models from very large historical databases. I published a textbook on fault detection and diagnosis as part of Springer Verlag's series on Advanced Textbooks in Control and Signal Processing [Book3]. The book includes a description of new fault detection and fault diagnosis algorithms [33,34] based on canonical variate analysis and Fisher discriminant analysis that outperform prior dimensionality reduction algorithms. The superior performance of the algorithms confirms theoretical analyses. We are currently developing algorithms that incorporate causal information into the data-driven process monitoring approach to enable the diagnosis of known, unknown, and multiple faults [46].

 

C. Simulation and Control of Crystallization Processes.  Controlling crystallization is especially challenging due to its strong dynamic nonlinearity and its high sensitivities to process conditions. The crystallization of pharmaceuticals has the additional challenge of having a tendancy to form undesirable needle-like or rod-like shapes from having widely-varying growth rates associated with the characteristic axes of the crystal. Also, there are no in situ sensors that can directly measure the multidimensional size distribution in the dense crystal slurries. Hence pharmaceutical crystals must be produced while having limited information on the states of the crystallization process.

An approach is being developed to control multidimensional crystal formation that incorporates first-principles models, optimal control, and new mathematical analysis techniques [52]. This approach incorporates a high resolution simulation algorithm to obtain both high computational efficiency and high accuracy for sharp multidimensional crystal size distributions [42,45,47,48]. Robust chemometrics (this is a form of multivariate statistics) relate on-line measurements and state/product variables, including the prediction of end-use properties from in situ laser backscattering measurements [35], and the on-line estimation of the solution concentration in dense crystal slurries using Attenuated Total Reflection-Fourier Transform Infrared (ATR-FTIR) spectroscopy [40,50,55]. The solution concentration estimates are more than an order-of-magnitude more accurate than those obtained in previous applications of ATR-FTIR to crystallization processes.  These estimates have been used with laser backscattering to identify the kinetics for secondary nucleation and growth for multi-coordinate crystals in dense crystal slurries in situ [44].

The first-principles modeling approach quantifies the accuracy of the model parameters, which is used by our analysis tools to quantify the accuracy of the model predictions [39]. The analysis tools produce accurate estimates of the worst-case and distributional dynamical behavior for finite-time nonlinear lumped and distributed parameter dynamical systems [53,60]. The robustness analysis approach is being incorporated into the design of optimal control recipes for batch crystallization [57-59]. Most of the techniques we have developed have been applied to pharmaceutical crystallizers at Merck [35,50,54].  A book is being written based on our approach for controlling multidimensional crystallization processes.

D. Analysis and Control of Microelectronics Processes.  Moore's law requires continual improvements in the microelectronics processes used to manufacture semiconductor devices. In collaboration with Prof. R.C. Alkire, we are creating methods for parameter sensitivity analysis, parameter estimation, and code-linking in multi-scale simulation codes that couple Monte Carlo simulation and finite different/element techniques [61-64]. The main applications of the methods are in copper electrodeposition, which is the process used to manufacture interconnects in various microdevices. This effort also includes the design of high performance feedback control systems to emulate experimental observations. In a separate collaboration with Prof. E.G. Seebauer, we have been carrying out parameter sensitivity and estimation studies for transient-enhanced diffusion, which is an unwanted process that occurs when the damage upon ion implantation in semiconductors is healed by annealing. Continuum simulation models have been implemented for the reaction and diffusion of the many interstitial and other species that influence dopant mobility. The parameters in these models are maximum likelihood estimates from data produced by experimental studies and density functional theory calculations reported in the literature, and experimental data collected by industrial collaborators [66-70].
