Industrial scale continuous stirred tank reactor (CSTR) for production and grade transitions of poly vinyl acetate (PVAc) at the different reactor sizes was investigated. Such reactor is known to show oscillatory behavior and to have periodic limit points, particularly at high molecular weights. Four efficient novel hybrid optimization methods which use variable population size genetic algorith...

This paper addresses the disturbance attenuation problem in nonlinear moving horizon control. Conceptually a minimax formulation with a general dissipation constraint is suggested and theoretical results on closed-loop dissipation, L2 disturbance attenuation and stability are discussed. The implementation issue is attacked with respect to tracking a reference trajectory in the presence of exter...

Fault diagnosis is a key task for developing safer control systems, especially in chemical plants. Nonetheless, acquiring good labeled fault data involves sampling from dangerous system conditions. A possible workaround to this limitation use simulation training data-driven systems. However, due modelling errors or unknown factors, may differ distribution real-world data. This setting known as ...
