Software for analytical nonlinear controller design

This paper presents a new software package that carries out symbolic manipulations to generate automatically analytical, model-based controllers and subsequently test the performance of the designed controller implemented on the process model. The software package has a user-friendly interface that was developed using Visual Basic and linked to MATHEMATICA using MathLink. The user enters the process model (set of ordinary differential and algebraic equations), and the software generates an analytical model-based controller (set of ordinary differential and algebraic equations), that can be in FORTRAN, C, or MATLAB format. The application and implementation of the software package are shown using a chemical reactor example
