We consider the problem of joint estimation of states and some constant parameters for a class of nonlinear discrete-time systems. This class contains systems that could be transformed into a quasi-LPV (linear parameter varying) polytopic model in the Takagi-Sugeno (T-S) form. Such systems could have unmeasured premise variables. a case usually overlooked in the observer design litera... https://www.jmannino.com/flash-pick-NHL-Edmonton-Oilers-Camo-iPhone-11-Pro-Max-Skin-p69200-super-choice/
