The uncertain continuous system with data loss is studied by using the switching control theories. Firstly, the working cases and the corresponding model of the continuous system with loss data are discussed. Then, the intermittent control is employed, namely during data continuous feedback, a control signal is applied to the system, and during the data continuously losing, the control signal is not exerted to the system. The uncertain control system with maximum data loss rate and external disturbance is studied by using the principle of switching control, and the controller design method is given in the form of the theorem. Finally, a simulation example is given to illustrate the effectiveness of the proposed method.
