Recommended Prerequisites

Calculus I, II, III, Linear Algebra and Analytic Geometry, Applied Computing, Modeling, Simulation and Optimization, Chemical Engineering Laboratories II.

Teaching Methods

Classes are used to introduce the concepts, definitions and formulations for elementary process modeling and the analysis of the dynamic behavior of chemical processes, together with the design and analysis of control systems. The application of these methodologies is demonstrated through examples, with the support of numerical simulation in the programming languages GNU Octave / Matlab / Mathematica.

Learning Outcomes

Understanding of the feedback and feedforward mechanisms, and their dissemination in systems of diverse nature. Formulation and application of mathematical models to identify and to characterize the dynamic behavior of a chemical process in view of its control. Application of control systems design and analysis methodologies. Knowledge of concepts and methodologies for the supervision of chemical process. The course aims at developing the following skills: Ability in analysis and synthesis; ability to formulate and solve problems; knowledge of programming and numerical simulation; Capacity of autonomous work and teamwork; Capability of critical thinking; Quality concerns; Competence in applying theoretical knowledge in practice in practice.
