The article is concerned with designing online identification algorithm for identification plunger model for  wicket gate of Kaplan turbine adaptive control system. Algorithm is based on generalised recurrent least square method and invariant embedding method. Computer modeling using designed algorithm and using real experimental data shows that algorithm is effective.  

Keywords: adaptive control system, diagnostic system, Kaplan turbine wicket gate, plunger, linearized models, identification, recurrent least square
