Abstract.
In this paper the design method of automatic control systems with rejection of disturbance influence based on Jordan controlled form (JCF) of nonlinear plants equations is presented. The method provides stability of nonlinear system and the desirable order of astatic to unmeasured external disturbances. The controller of the system includes the state estimation of the equivalent expanded system and a number of additional integrators. The number of there integrators is defined by a point of the applying of disturbances to plant and the desirable order of the astatic. The numerical example of nonlinear control system design is given.
Key Words:
nonlinear plant, astatic control, disturbance, equivalent system, observer.
KONSTRUISANJE KONTROLNIH SISTEMA SA UKLANJANJEM POREMEĆAJA BAZIRANOM NA JCF NELINEARNIH PLANTNIH JEDNAČINA
U ovom radu predstavljen je model konstruisanja automatskih sistema koji poseduju mogućnost odbacivanja remetilačkog uticaja a koji je baziran na Jordan kontrolnom obliku (JCF) nelinearnih plantnih jednačina. Ovaj metod pruža stabilnost nelinearnih sistema kao i optimalnu veličinu promenljivosti neizmerenih spoljašnjih poremećaja. Kontroler sistema uključuje procenu ekvivalentnog proširenog sistema i određeni broj dodatnih integratora. Broj ovih integratora definisan je primenom poremećaja i željenim redom astatika. Dat je i numerički primer nelinearnog kontrolnog sistema.
