A Kalman filter based robust model predictive control with constraints

Abstract In this paper, a new model predictive control method (MPC) derived from the modification of Generalized Predictive Control (GPC) is proposed. Firstly, a Kalman filter based predictor is introduced. Secondly, a time-dependent weighting factor is newly introduced into the MPCs cost function to improve the transient responses. The cost function is also extended by adding a new term related to the reference tracking error of the manipulation variables to handle redundant manipulation variables. Thirdly, a parameter tuning method considering robust stability of the control system is proposed. Consequently a constrained control type algorithm for a MIMO plant is formulated.
