Abstract
V prispevku je predstavljena sinteza podoptimalnega krmilnika, ki sloni na resitvi algebraične Riccatijeve enačbe (ARE). Predstavljen je numerični postopek, s katerim lahko pridemo do te rešitve. V praksi se parametri krmiljenega sistema mnogokrat precej razlikujejo od tistih v ARE. V tem primeru sta vprašljivi optimalnost in celo stabilnost krmilnega sistema. Zelo uporabno bi torej bilo, èe bi lahko zasnovali prilagodljivi linearni podoptimalni krmilnik. Tak krmilnik bi bil zmozen odkriti spremembe v parametrih sistema in prirediti parametre.

Title:Programmable logic controllers based on the algebraic Riccati equation solution
Abstract:
This paper deals with the synthesis of a suboptimal controller, based on the solution of the algebraic Riccati equation (ARE). The numerical procedure for obtaining the solution is presented. In applications the controlled system parameters often differ from the ones used in the ARE. In this case the optimality of the control system and even its stability are questionable. Therefore, it would be very useful to design an adaptive linear suboptimal controller. Such a controller should be able to detect changes in the system parameters and adjust its parameters.

Keywords:adaptive systems, Riccati equations, programmable logic controllers, numerical algorithms
