Designing Two-axis Gimbaled Control Systems for Observation Units Stabilization

This article presents features of designing a two-axis inertially stabilized platform assigned for stabilization of observation units and devices, for example, cameras. The problem of stabilization of images is analysed, including electromechanical, optical, mechanical, and computer techniques. The appropriate structural diagrams are represented. The procedure of the synthesis for the inner and outer tracking loops of the control system is represented. The structure of control laws is proposed. The combined optimization criteria that ensure compromise between the tracking accuracy and resistance to disturbances on angular rate are represented. The structures of the synthesised regulators are described. The results of the synthesized system simulation are shown. The analysis of the simulation results is given. The system’s norms are calculated. The obtained results can be used in the area of stabilization of a wide class of instrumentation assigned for operation on moving objects.
