Output feedback and tracking in nonlinear model predictive control

The development of efficient output feedback Model Predictive Control algorithms for nonlinear systems with stability properties and tracking capabilities is an active area of research and represents a promising field for innovative industrial applications. In this talk, this problem is addressed by resorting to the classical combination of a state feedback control law and a state observer, e.g. an Extended Kalman Filter. Different control schemes are analyzed under the assumption that the reference signal to be tracked is piece-wise constant. It is shown that the adopted control structure deeply influences the stability and robustness results achievable and leads to implementations where state and control constraints can be included at different levels of complexity. Moreover, the control of non square systems can only be done provided that the proper control structure is selected
