Fall 2017  ChE (401) - Chemical Process Dynamics and Control (Total Credits: 3)    

Topics: steady and unsteady-state behavior of chemical processes; transfer function and block diagram; fundamental feedback and feedfoward control strategies; control design and applications; process optimization; process modeling and problem solving with Excel, MATLAB and Simulink; process data analysis and empirical modeling (e.g., machine learning).   Objectives: after taking this course, students should be able to: 1) understand and apply process control theory; 2) develop and resolve models for chemical processes; 3) analyze and regulate the process dynamics; 4) learn co

MATLAB and Simulink.
