Global optimality in model predictive control via hidden invariant convexity
Jorn H. Baayen, Krzysztof Postek
Non-convex optimal control problems occurring in, e.g., water or power systems, typically involve a large number of variables related through nonlinear equality constraints. The id…
Mixed-Integer Path-Stable Optimisation, with Applications in Model-Predictive Control of Water Systems
Jorn Baayen, Jakub Marecek
Many systems exhibit a mixture of continuous and discrete dynamics. We consider a family of mixed-integer non-convex non-linear optimisation problems obtained in discretisations of…
A continuation approach to the optimization of hydropower operations
Jorn H. Baayen, Julia Rauw, Teresa Piovesan
The instantaneous power generation from a hydroelectric turbine is proportional to the product of head difference and turbine flow. The equation relating power to hydraulic variabl…
Continuation method for PDE-constrained global optimization: Analysis and application to the shallow water equations
Jorn Baayen, Teresa Piovesan, Jesse VanderWees
This paper shows how a class of non-convex optimization problems constrained by discretized nonlinear partial differential equations may be solved to global optimality using an int…
Trajectory tracking control of kites with system delay
Jorn H. Baayen
A previously published algorithm for trajectory tracking control of tethered wings, i.e. kites, is updated in light of recent experimental evidence. The algorithm is, furthermore,…
Vortexje - An Open-Source Panel Method for Co-Simulation
Jorn H. Baayen
This paper discusses the use of the 3-dimensional panel method for dynamical system simulation. Specifically, the advantages and disadvantages of model exchange versus co-simulatio…
Tracking control with adaption of kites
Jorn H. Baayen, Wubbo J. Ockels
A novel tracking paradigm for flying geometric trajectories using tethered kites is presented. It is shown how the differential-geometric notion of turning angle can be used as a o…
