“…As to non-CVRT control, the works under the term intelligent control have mainly appeared in the forms of hierarchical intelligent control architectures (Saridis, 1989;Kumar and Stover, 2000;Phoha et al, 2001), hierarchical control architectures of intelligent systems (Albus and Meystel, 2001;Meystel and Albus, 2002); control-loop nested architecture of large complex systems (Tianfield, 2001a(Tianfield, , b, 2002; distributed/decentralized control architectures (Heragu et al, 2002), architectures of expert control and knowledge-based control (Å rze´n, 1989;Linkens et al, 2000), supervisory control (Gonza´lez et al, 1998;Acosta et al, 2001), industrial process integrated automation (comprising CVRT control, set-point optimization, sequence logic control at start/stop, scheduling, planning, managing, etc.) (Badami et al, 1991;Ja¨rvensivu et al, 2001).…”
