Electricity in the Air: Insights From Two Decades of Advanced Control Research and Experimental Flight Testing of Airborne Wind Energy Systems

Vermillion, Chris (author), Cobb, Mitchell (author), Fagiano, Lorenzo (author), Leuthold, Rachel (author), Diehl, Moritz (author), Smith, Roy S. (author), Wood, Tony A. (author), Rapp, S. (author), Schmehl, R. (author)

Airborne wind energy systems convert wind energy into electricity using tethered flying devices, typically flexible kites or aircraft. Replacing the tower and foundation of conventional wind turbines can substantially reduce the material use and, consequently, the cost of energy, while providing access to wind at higher altitudes. Because the...

Adaptive compensation of measurement delays in multi-sensor fusion for inertial motion tracking using moving horizon estimation

Girrbach, Fabian (author), Kok, M. (author), Zandbergen, Raymond (author), Hageman, Tijmen (author), Diehl, Moritz (author)

Robust and accurate pose estimation of moving systems is a challenging task that is often tackled by combining information from different sensor subsystems in a multi-sensor fusion setup. To obtain robust and accurate estimates, it is crucial to respect the exact time of each measurement. Data fusion is additionally challenged when the...

Towards in-field and online calibration of inertial navigation systems using moving horizon estimation

Girrbach, Fabian (author), Zandbergen, Raymond (author), Kok, M. (author), Hageman, Tijmen (author), Bellusci, Giovanni (author), DIehl, Moritz (author)

Inertial sensors are used in an increasing number of autonomous applications. Integrating such sensors into dynamic systems, the problem of their calibration arises naturally. Existing methods often require the sensor to be accurately placed in certain poses, which can be infeasible in practice. In this paper, we present an optimization-based...

Warping model predictive control for application in control of a real airborne wind energy system

Lago, Jesus (author), Erhard, Michael (author), Diehl, Moritz (author)

Fast online generation of feasible and optimal reference trajectories is crucial in tracking model predictive control, especially for stability and optimality in presence of a time varying parameter. In this paper, in order to circumvent the operational efforts of handling a discrete set of precomputed trajectories and switching between them,...
