Disturbance Observer-Based Predictive Tracking Control of Uncertain HOFA Cyber-Physical Systems

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.
