To the single axis control model of the stabilized platform, the sliding mode rule is founded. The value of extraneous disturbances is estimated by using GM (1, 1) grey prediction algorithm, and then it is added to the sliding mode control rule as the compensating part. At the same time, the value of the switching function is predicted by the grey prediction method, by which the control chattering phenomenon is reduced greatly.
