In this work we have designed a signal based K-exponentially stable frequency estimator for the estimation of the wave encounter frequency at sea. The frequency estimator under consideration is a second-order filter designed for the estimation of the

Parametric roll is a dangerous resonance phenomenon for ships caused by time-varying restoring forces. The resulting large roll oscillations may endanger the ship's safety and possibly lead to capsizing. The susceptibility of container ships to param

This paper proposes a robust control approach to stabilize roll parametric resonance, a dangerous nonlinear resonance phenomenon for ships. To that matter, we extend a recent extremum seeking speed and heading control strategy to stabilize roll param

In this chapter, two strategies to actively control ships experiencing parametric roll resonance are proposed. Both approaches aim at changing the frequency of the parametric excitation by controlling the Doppler shift, which, in recent results, has

In this work, a control strategy for ship parametric roll resonance is developed by changing the frequency of the parametric excitation. This is achieved by varying the ship’s forward speed. This changes the perceived frequency of the waves, known

In this work, we develop a ship model for parametric roll resonance under non-constant speed. Variations in speed changes the encounter frequency, i.e., the Doppler-shifted frequency of the waves as seen from the ship. Commonly, a Mathieu-type equati
