Abstract
This thesis presents a multidisciplinary design optimisation (MDO) framework for gimbal-based acquisition, tracking, and pointing (ATP) mechanisms used in laser satellite communication systems. The research combines two topology optimisations, bearing models, and system-level coupling to enable the simultaneous optimisation of multiple interacting components within a unified framework.
The proposed methodology captures the interaction between structural stiffness, mass distribution, bearing behaviour, and launch performance, moving beyond conventional component-level optimisation approaches. Different coupling and optimisation strategies are investigated, including reduced-order modelling and gradient-based optimisation techniques, to evaluate the trade-off between computational efficiency and physical accuracy. This thesis demonstrates how multidisciplinary optimisation can support the development of lightweight, high-performance gimbal systems for future optical communication applications.
