	SYST0011-2   Dynamics and control of chemical systems Duration :   20h Th, 15h Pr Credits/ECTS :   Master in Chemical Engineering and Materrial Sciences, in-depth approach, 2nd year First semester 3 Holder(s) :   Georges Heyen Language :   French language Course contents :   Dynamic modelling of chemical systems Revision on Laplace transform Flowchart analysis and transformation Model linearisation Identification of reduced models from a measured response curve Transfer functions Frequency response analysis, Bode diagram Control actions : PID control Stability of controlled systems Tuning PID controllers Influence of dead time on control quality Synthesis based on stability : gain and phase margins Feed forward control. Cascade control Introduction to multivariable control : variable coupling, RGA analysis, decoupling Introduction to digital control systems Course objective :   Introduction to practical methods used to control chemical processing operations (heat exchange, reactors, distillation) Gaining notions allowing a chemical engineer to discuss with a control engineer Prerequisites :   Modelling of basic unit operations (reactors, heat exchangers) both in steady state and in dynamics Solving differential equation systems (linear and non-linear) Workshops :   Illustration of concepts discussed during the lectures using simulations (using dynamic simulation software) Identification of an approximate model from an experimental response curve. Tuning the parameters of a PID controller; influence of parameters on control efficiency. Some more complex control schemes : feedforward, cascade control, decoupling.
