- Abstract
- This paper presents some considerations regarding the influence of parameters estimation algorithms relative to the performances of an adaptive control system. There were considered two types of parameters estimators: the classical recursive least square (RLS) estimator and respectively, a non-recursive estimator based on Givens orthogonal transformation. All study cases considers as plant a synchronous generator connected to an infinite bus through a long transmission line. There is presented a mathematical model of the considered synchronous generator process and it is also described the implementation algorithm of the non-recursive parameters estimator based on Givens orthogonal transformation. The comparative studies are conducted considering the both cases of an open and a closed loop structure's influence over the parameters estimation. Also a comparative study is done regarding the usage of RLS estimator and respectively the non-recursive estimator based on Givens orthogonal transformation. The simulation results show that the evolution of the estimated parameters doesn't represent a trustful criterion for evaluating the control system performances. Therefore, in the same simulation conditions using different parameters estimators the simulations show different temporal evolutions of the estimated process parameters.
