Henson 9502327 This is a Faculty Early Career Development (CAREER) grant which includes both a research as well as an educational component. Research: The PI's research focuses on the development of nonlinear output feedback control strategies for constrained multivariable processes. More effective estimation and control techniques are needed for chemical processes as a result of increased demands on productivity and product quality. In order to provide satisfactory performance, industrial control systems must account for multiple inputs and outputs, nonlinear dynamic behavior, process constraints, and lack of on-line measurements. The objective of this research is to develop a computationally efficient control strategy for chemical processes that exhibit these characteristics. The control system has three distinct components: (1) a nonlinear closed-loop observer which provides on-line estimates of unmeasured state variables; (2) a multivariable input-output linearizing controller which accounts for process nonlinearities; and (3) a multivariable linear model predictive controller which compensates for process constraints. The control strategy will be analyzed theoretically and evaluated via simulation using representative chemical and polymerization reactor models. A collaborative arrangement with DuPont will allow the control scheme to be applied to an industrial polymerization process. This test will facilitate technology transfer to industry. Education: The teaching plan is designed to enhance the educational opportunities available in the Louisiana State University Chemical Engineering Department. The specific goals of the plan are to: (1) improve the department's computer facilities; (2) revise the curriculum for the department's process control courses; (3) computerize experiments in the department's undergraduate laboratories; (4) revitalize the department's undergraduate research program; (5) establish a minority student program in the department; and (6) participa te in the department's graduate student recruitment program.

亨森 9502327 这是一个教师早期职业发展（CAREER）补助金，其中包括研究以及教育组成部分。 研究：PI的研究重点是约束多变量过程的非线性输出反馈控制策略的发展。 随着对生产率和产品质量要求的提高，化工过程需要更有效的估算和控制技术。 为了提供令人满意的性能，工业控制系统必须考虑多个输入和输出，非线性动态行为，过程约束，以及缺乏在线测量。 本研究的目的是开发一种计算效率高的控制策略，表现出这些特点的化学过程。 该控制系统有三个不同的组成部分：（1）一个非线性闭环观测器，它提供在线估计的不可测的状态变量;（2）一个多变量的输入输出线性化控制器，它占过程的非线性;和（3）一个多变量的线性模型预测控制器，它补偿的过程约束。 控制策略将进行理论分析和评估，通过模拟使用代表性的化学和聚合反应器模型。 与杜邦公司的合作安排将使控制方案适用于工业聚合过程。 这项试验将促进向工业界转让技术。 学历：该教学计划旨在提高路易斯安那州立大学化学工程系的教育机会。 该计划的具体目标是：（1）改善系的计算机设施;（2）修订系的过程控制课程;（3）在系的本科生实验室进行计算机实验;（4）振兴系的本科生研究计划;（5）在系建立少数民族学生计划;（6）在系中建立一个计算机实验室。（6）参加系研究生招生计划。
