A kernel proof of the De Cock-De Moor Lyapunov identity
Jonas Gillberg, Johan Löfberg
We prove the rank-one Lyapunov spectral identity recorded as Problem 9.1 in the 2004 collection of unsolved problems in mathematical systems and control theory. Let solve t…
A characteristic function framework for chance constraint programming in stochastic model predictive control
Yuwei Ying, Johan Löfberg, Anders Hansson
The computation of chance constraints in stochastic model predictive control is often numerically challenging due to the non-Gaussian nature of the disturbances. To overcome this p…
Fast or Cheap: Time and Energy Optimal Control of Ship-to-Shore Cranes
Filipe Marques Barbosa, Anton Kullberg, Johan Löfberg
This paper addresses the trade-off between time- and energy-efficiency for the problem of loading and unloading a ship. Container height constraints and energy consumption and rege…
Time-optimal control of cranes subject to container height constraints
Filipe Marques Barbosa, Johan Löfberg
The productivity and efficiency of port operations strongly depend on how fast a ship can be unloaded and loaded again. With this in mind, ship-to-shore cranes perform the critical…
Model Reduction using a Frequency-Limited H2-Cost
Daniel Petersson, Johan Löfberg
We propose a method for model reduction on a given frequency range, without the use of input and output filter weights. The method uses a nonlinear optimization approach to minimiz…
