Analysis and Control of the ALSTOM Gasifier Problem

3.1    GASIFIER SYSTEM DESCRIPTION AND NOTATION

With an understanding of MATLAB and Simulink, the next step is to apply the knowledge onto real systems. There are many control systems in industry. The control systems design encompasses not only the PID controller (which we have studied previously), it also includes precontrollers design activities such as scaling the ill- conditioned system, selecting the optimal input and output pairs to reduce the level of coupling between them, and model-order reduction to reduce the size of the system to be controlled.

To demonstrate this, one of the selected applications is on the ALSTOM gasifier used in power generation. ALSTOM developed a benchmark ...
