Nod-over-Roll is a commonly used gimbal configuration in automatic target tracking and pointing systems due to its simplicity and volumetric advantage. Yet, it suffers from an inherent kinematic singularity problem right at the center of its task space, where roll axis and pointing vectors coincide. This phenomenon is called zenith pass problem and has to be solved in real time for a proper tracking performance. This thesis focuses on the zenith pass problem from an air-to-air missile seeker perspective. An estimator-based novel algorithm and a simulation environment has been developed. The performance of the proposed algorithm has been verified by a series of engagement scenario tests performed in comparison with available zenith-pass algorithms in the literature.

Kinematic analysis of imaging seekers with roll-over-nod gimbal and a folded electro-optical layout Kandemir, Kutlu D.; Yazıcıoğlu, Yiğit; Ozkan, Bulent (2019-01-01) Nod-over-roll is a commonly used gimbal configuration especially in air-to-air missile seekers due to its volumetric advantage. It may further scaled down by implementing a folded optical layout and locating the detector off-gimbal. Yet, the concept suffers from an inherent kinematic singularity problem right at the center of its task space, where roll axis and pointing vectors coincide. The phenomenon is called zenith pass problem and has to be solved in real time for proper target tracking. A second drawb...
Cogging Torque Disturbance Rejection for a Low-cost Gimbal Motor and a Controller Design with Practical Considerations Ozdogan, Gokhan; Leblebicioğlu, Mehmet Kemal (2019-01-01) In many robotic applications and inertially stabilized electro-optic gimbal systems, precise positioning and speed control are highly important concepts. Due to size and weight limitations, motor is required to be small but torque density is desired to be high. In high torque and cheap PMSM and BLDC motors, cogging torque and friction are usually the challenging disturbance sources. In this study, cogging torque and friction are identified using position sensors which already exist in gimbal systems, so the...
Dynamic modelling and control of a gimballed airborne antenna platform with mass unbalance and friction Şeref, Tuğçe; Leblebicioğlu, Mehmet Kemal; Department of Electrical and Electronics Engineering (2018) Inertial stabilized gimballed systems are widely-used in many applications to achieve a high precision positioning. Airborne antennas pointing target as a part of the satellite communication may be examples of such systems. This thesis presents the dynamic modelling and control of a two axes gimballed airborne antenna platform. First, reference frames and the transformation matrices are defined to build up the motion of the antenna and kinematic equations of each gimbal are derived. Next, the dynamic equati...
Line-of-sight stabilization of a gimbaled mechanism under passive base isolation Kandemir, Kutlu Demir; Akmese, Alper; Yazıcıoğlu, Yiğit (2014-01-01) Line-of-sight stabilization is an important concept for aerospace applications utilizing gimbaled imaging systems. A widely used method for protecting the line-of-sight stabilization system from the disturbing effects of the base vibrations is to mount it on passive vibration isolators. However, these isolators may interact with gimbal controller and drastically limit the stabilization performance. This work deals with line-of-sight stabilization problem in aerospace structures by focusing on the parameters...
Trajectory tracking control of parallel robots in the presence of joint drive flexibility Ider, S. Kemal; Korkmaz, Ozan (Elsevier BV, 2009-01-09) Trajectory tracking control of parallel manipulators is aimed in the presence of flexibility at the joint drives. Joint structural damping is also considered in the dynamic model. The system is first converted into an open-tree structure by disconnecting a sufficient number of unactuated joints. The closed loops are then expressed by constraint equations. It is shown that, in a parallel robot with flexible joint drives, the acceleration level inverse dynamics equations are singular because the control torqu...
