The **Kalman** **filter** is an iterative Bayesian estimation algorithm useful to estimate system states from sequential, noisy measurements. From a currently estimated state, the state in the next time step is predicted by a state transition model, which describes the theory of the dynamic system behavior. In this **paper** an approach is proposed by incorporating the unscented **Kalman** **filter** into the NMPC problem, which propagates uncertainty introduced from both the state estimate and additive noise from disturbances forward in time. The feasibility is maintained through probabilistic constraints based on the Gaussian approximations of the state.
