This letter extends the unified observer design problem to the class of Nonlinear Parameter Varying (NLPV) systems with parameter dependence in both the dynamics and the control input matrices. First, parameterization of the observer matrices, herein generalized for the NLPV case, allows us to decouple the input disturbance from the estimation error. Then, the vanishing disturbance caused by the nonlinearity is bounded by the Lipschitz property and the effect of measurement noise on the error is minimized using the generalized
