Dear Editor， In this letter， an output tracking control problem of uncertain cyber-physical systems (CPSs) is considered in the perspective of high-order fully actuated (HOFA) system theory， where a lumped disturbance is used to denote the total uncertainties containing parameters perturbations and external disturbances。 A disturbance observer-based HOFA predictive control (DOB-HOFAPC) is adopted to achieve the desired tracking control performance and compensate for the communication delays in the forward and backward channels。 The further discussion gives a criterion to analyze the tracking performance and stability of closed-loop CPSs。 An example of long distance power transmission line is shown to verify the feasibility of the proposed DOB-HOFAPC。
