Nonlinear Dynamics Decoupling Control for a Light and Small Inertially Stabilized Platform*

The three-axis inertially stabilized platform (ISP) can effectively isolation disturbance inside and outside the aircraft, and create a stable working environment for the aerial remote sensing system. ISP usually uses three-axis frame structure to isolate the aircraft attitude angle motion, but the frame coupling effect has an important effect on the high-accuracy control of the ISP. In this essay, method of adaptive composite decoupling controller on the basis of inverse system model reference is came forward to realize the high-accuracy decoupling control of the three-axis ISP.
