An estimation of the state and the unknown inputs of the reduced nonlinear model of an activated sludge process using the Extended Kalman Filter (EKF) is proposed. First, we present the reduced nonlinear model. This model contained five state variables and four unknown inputs. For satisfying the rank condition for the construction of an EKF, one unknown input has been approximated and the daily mean...
This paper deals with the observer-based compensator design for bilinear systems. A saturated quadratic control law is used with two kinds of LPV observers. The closed loop stability is achieved using results on large scale systems.
