Design of Adaptive Observer Applied to M.R.A.C. by Selection of State Variable Filter

상태변수 필터 선정에 의한 적응 관측기의 설계 및 기준모델 적응제어

In this paper, an adaptive observe based upon the exponentially weighted least-squares method is implemented in the design of a model reference adaptive controller for an unknown time-invariant discrete single-input single-output linear plant. A method of selecting the state variable filter is proposed. In this scheme, all the past data are weithted exponentially with the weighting coefficient.
