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.

Henson 9502327 这是一项教师早期职业发展 (CAREER) 补助金，其中包括研究和教育部分。 研究：PI 的研究重点是针对约束多变量过程的非线性输出反馈控制策略的开发。 由于对生产力和产品质量的要求不断提高，化学过程需要更有效的估计和控制技术。 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。 本研究的目的是为具有这些特征的化学过程开发一种计算有效的控制策略。 该控制系统具有三个不同的组件：（1）非线性闭环观测器，提供未测量状态变量的在线估计； (2) 考虑过程非线性的多变量输入输出线性化控制器； (3) 多变量线性模型预测控制器，用于补偿过程约束。 控制策略将从理论上进行分析，并通过使用代表性化学和聚合反应器模型的模拟进行评估。 与杜邦公司的合作安排将允许该控制方案应用于工业聚合过程。 该测试将促进技术向工业转移。 教育：该教学计划旨在增加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）改善部门的计算机设施； （二）修订本系过程控制课程设置； （三）本系本科生实验室实验计算机化； （四）振兴本系本科生科研项目； （五）在系内设立少数民族学生项目； （六）参与院系研究生招生计划。
