Abstract
The aim of the gimballed stabilization system is to stabilize the sensor's line of sight towards a target by isolating the sensor from the disturbance induced by the operating environment, such as various disturbance torques and body motions. This paper presents a two axes gimbal assembly. The torque relationships are derived considering the angular motion of the base body and the dynamic unbalance. The stabilization loops for the two axes gimbal system are constructed and related to each other with a cross-coupling unit. Next, the overall model is simulated using two approaches and the obtained results are compared to show the correction of the model proposed. Finally, numerous tests are applied to evaluate the model's performance and investigate the effects of torque disturbance considered in this research.

Utilizing (18) and (35), the global torque relationships of the two axes gimbal system introduced on the assumption that gimbals have no dynamic unbalance can be clarified by a block diagram, as indicated in figure 5
Summary
Optical equipment (such as IR, radar, laser, and television) has seen wide use in many important applications, such as image processing, guided missiles, tracking systems and navigation systems. This article is devoted to the presentation of a model of a two axes gimbal system in order to simplify the picture of the gimbal systems and further investigate the properties of this configuration by taking into account the most important disturbance sources, such as the base rotations, the gimbal system imperfections and the gimbal system properties In another words, the motivation and importance of this research results from deriving the torque relationships by considering the angular motion of the base body and the dynamic mass unbalance, and introducing the overall control system with cross-coupling. The motivation and importance of this research results from deriving the torque relationships by considering the angular motion of the base body and the dynamic mass unbalance, and introducing the overall control system with cross-coupling This is what can provide more understanding of the activity of such systems wherever they are designed considering the most important work conditions. The results are discussed, concluding remarks are made, and some future works are suggested so as to develop this research
