© 2024 European Control AssociationIn this paper， a new output feedback integral sliding model predictive control (OF-ISMPC) strategy is proposed for linear discrete-time systems when the states are unmeasured， which avoids the utilization of a state observer。 The proposed OF-ISMPC can ensure strong robustness while at the same time achieving optimal performance of the controlled system。 The role of the output feedback integral sliding mode control (OF-ISMC) is to compensate for any matched disturbances。 The role of the output feedback robust model predictive control (OF-RMPC) is to solve the optimization problem with constraints。 Moreover， the impact of unmatched disturbances on the system is reduced by defining the integral sliding surface as a function of an optimal projection matrix。 The input-to-state practical stability for the closed-loop system is proved。 Finally， numerical simulations and experimental results are provided to validate the effectiveness of the proposed approach。
