Robust Decentralized Pid Controller : a Case Study
نویسنده
چکیده
Robust stability is an important aspect in control of real world systems, since uncertainties have to be considered in dynamic system model. This paper studies the robust decentralized controller design for case study: quadruple tank process, [3,4]. Several important aspects of system analysis are shown to choose appropriate pairing and assess stabilizability via decentralized control structure; the main contribution is in decentralized discrete-time controller design. Simulation results illustrate the obtained results and their qualities. Abstrakt Robustná stabilita je dôležitou stránkou pri návrhu riadenia reálnych systémov. Tento príspevok sa zaoberá návrhom robustného decentralizovaného regulátora pre prípadovú štúdiu: systém štyroch nádrží, [3,4]. Príspevok ilustruje niektoré dôležité aspekty analýzy systému potrebné na správny výber párovania vstupov a výstupov umožňujúci stabilizáciu systému decentralizovaným riadením; hlavným prínosom je návrh decentralizovaného diskrétneho algoritmu riadenia. Výsledky simulácie ilustrujú vlastnosti získaných regulátorov.
