Very Large Scale Integrated Optical Interconnects: Coherent Optical Control Systems with 3D Integration

Transforming basic multi-disciplinary research into applied research in the area of a new generation of networks, sensors, cyber-physical, and edge-cloud systems used for cyber space is a difficult task. However, moving even a step forward by providing advanced field and testing facilities for ground-air demonstrations for appearing Aviation 4.0 scenarios is a real challenge. In our opinion, such a rapid and dynamic process should be powered by many research and infrastructure projects. New development strategies are needed in the upcoming future to link emerging trends in information and communications technologies together with increased competitiveness and users expectations from fully autonomous drones, robots, cars, etc. This paper aims to share our early experiences in setting and providing distributed testbeds to cross different hardware, software, and cyber-physical components and pave the way for air-ground demonstrations of the new emerging IT paradigm – digital continuum. We also share our vision of implementing virtual and digital spaces at a large scale by the gradual transition towards higher levels of cyber-physical systems automation and autonomy. Finally, we promote dynamic, data-driven, service-oriented approaches and network-centric platforms for a new generation of air and ground control systems which will be validated in real conditions established thanks to our new airfield-based laboratories used in many ongoing and future R&D projects.

An optimization method is proposed for the simultaneous design of structural and control systems using the equivalent static loads. The two structural and control systems are not completely independent and need to be considered in a unified fashion. Furthermore, an integrated system design is unavoidable to exhibit a good performance in the time domain. The analysis for the integrated system is conducted for the transient-state in a dynamic manner. The constraints for the structural and control systems are defined in the time domain as well. Therefore, a physically small scale problem in structural analysis easily becomes quite a large scale in an optimization problem. A new equivalent static loads (ESLs) method, which deals with the structural design variables as well as the control design variables, is proposed to solve physically large scale problems. A finite element dynamic equation is defined with control forces and a dynamic response optimization problem is formulated. Linear static response optimization is carried out with the ESLs. The control forces for the linear static response optimization are considered as design variables. Shape variables are utilized to handle the design variables for the control forces. Several examples are solved to validate the proposed method.
