Self-Powered Dynamic Systems in the Framework of Optimal Uncertainty Quantification

Abstract

The energy that is needed for operating a self-powered device is provided by the energy excess in the system in the form of kinetic energy, or a combination of regenerative and renewable energy. This paper addresses the energy exchange issues pertaining to regenerative and renewable energy in the development of a self-powered dynamic system. A rigorous framework that explores the supply and demand of energy for self-powered systems is developed, which considers uncertainties and optimal bounds, in the context of optimal uncertainty quantification. Examples of regenerative and solar-powered systems are given, and the analysis of self-powered feedback control for developing a fully selfpowered dynamic system is discussed.

Self-Powered Solar Aerial Vehicles: Towards Infinite Endurance UAVs

“…They are capable of using renewable energy resources, or harvesting the excessive kinetic energy in the system using regenerative techniques, or a combination of the two ([13]- [16], [22]). In the present context self-powered dynamic systems are associated with the solar-powered UAVs (Brunel Quadrotor, Octorotor, and Trirotor UAVs [13], [15], [17]- [21]). It is important here to investigate the energy consumption of the UAV as a function of the duty cycle, and provide a reference and approach to identify the self-powered conditions in terms of inputs, outputs, and parameters of the system.…”

“…Three solar-powered vehicles known as Brunel Quadrotor, Octorotor, and Trirotor solar powered UAVs ( [13], [15], [17]- [21]) have been developed for achieving self-sustained systems in terms of energy in the framework of 'Self-powered Dynamic Systems' ([13]- [16], [22]). This framework seeks to realize dynamic systems powered by their excessive kinetic energy, renewable energy sources, or a combination of both.…”

“…Brunel Solar UAVs ( [13], [15], [17]- [21]) are novel systems designed to realize long endurance flight and autonomy. The multirotor configurations along with solar power, autonomy, and small size buoyancy hull make them unique systems.…”

“…This paper explores conditions and scenarios for developing Selfpowered Solar UAVs as energy independent vehicles in accordance to dynamics, control system and accessible solar energy of the vehicles. The concept of Self-powered Dynamic System ([13]- [16], [22]) in the framework of Optimal Uncertainty Quantification ( [48], [13], [15]) is applied here. OUQ [48] takes uncertainties and incomplete information in the dynamics, control, available energy, and electrical power demand of the system into account, and provide optimal solutions in attaining self-powered control and maneuvering with sustainable energy independent condition.…”

Energy harvesting from suspension system and self-powered vibration control for a seven degree of freedom vehicle model

“…In Khosnoud et al., 19,20 Nakano et al., 13 and Shimura et al., 14 a theoretical analysis of a self-powered active suspension system is presented. For simplicity, a 2 DoF car suspension model and a sky-hook controller are used to enable an analytical evaluation of the energy balance of the system.…”
