PROCESS CONTROLA.Y. 2008/2009
Hours for week: 5 - Weeks: 12
Hours of lectures: 50 - Hours of laboratory: 3 - Hours of others activities: 2
Notions on dynamic process modeling. Balance equations and constitutive equations. Hydraulic processes, chemical processes, thermal processes.
P&I diagrams and notation. Industrial controllers. PWM control. One degree of freedom control schemes. Two degrees of freedom control schemes. Ratio control. Smith predictor. Direct sensitivity and complementary sensitivity.
Describing function. Relay, hysteresis and saturation describing functions. Self tuning of industrial controllers through permanent oscillations.
Multivariable linear systems. MIMO systems control. Measurable disturbances compensation. Forward and backward decoupling controllers. Zeros and poles of linear MIMO systems. Generalized Nyquist criterion.
The aim of the course is to illustrate the main non classic control tecniques applied to the process control. The course has a part of numerical simulation by which the student applies the techniques learnt during the course.
Lectures and numerical simulations.
