Abstract
A dual stage control system for inertially stabilized platform can be represented by a multi-input multi-output (MIMO) system which often consists of a gyro-stabilized platforms as the coarse stage and an additional servo mechanism in the imaging optical path as the fine stage. This paper presents a robust MIMO controller, which focused on the systematic design method not only for the fine stage but also for the coarse stage. And by considering the obvious difference of the model uncertainties and bandwidths between the two stages, the frequency separation design can be obtained by the well-defined weighting functions. The proposed controller can achieve both good tracking performance and overall system stability. Simulations indicate that the proposed controller can effectively improve the steady state tracking performance and overall system stability.
