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.inmuebleslasmercedes.com/product-category/accessories-insulated-food-beverage-copyright-parts/
