Description
  • The paper deals with continous-time adaptive control of a multi input - multi output nonlinear process. A nonlinear model of the process is approximated by a continuous-time external linear model. The parameters of the CT external linear model are recursively estimated via an external delta model with the same structure as the CT model. The control system configuration with two feedback controllers is considered. Design of controllers is based on operations in the ring of polynomial matrices. Resulting proper controllers ensure asymptotic tracking of step references and step load disturbances attenuation. A control quality is achieved using the exact pole placement method as well as by selectable weight matrices dividing weights among numerators of transfer functions of subcontrollers. The control is tested on a two input - two output nonlinear process represented by a model of two spheric liquid tanks in series.

  • Článek se zabývá adaptivním řízením mnoharozměrového systému. Nelineární model procesu je aproximován externím lineárním modelem, jehož parametry jsou průběžně odhadovány pomocí delta modelu se stejnou strukturou. Je uvažována struktura systému řízení se dvěma zpětnovazebními regulátory. Tyto jsou odvozeny pomocí operací v okruhu polynomiálních matic. Výsledné ryzí regulátory zajišťují asymptotické sledování referenčních signálů i úplnou kompenzaci poruch. Kvalita řízení je dosahována exaktním přiřazením pólů i koeficienty, rozdělujícími váhy mezi čitatele přenosů subregulátorů. Algoritmus řízení je ověřen simulacemi na nelineárním modelu zásobníků na kapaliny. (cs)
