Explicit model predictive control with time varying constraints for collective pitching in large wind turbines

IECON 2016 - 42nd Annual Conference of the IEEE Industrial Electronics Society, 2016
Control of collective pitching for large wind turbines is considered. This paper introduces two main contributions: 1) the design of explicit model predictive control with time varying constraints on boundaries of and limits on the rate of change of the control action and 2) the application of the developed explicit model predictive control for the ...

Optimal control of an autonomous underwater vehicle equipped with the collective and cyclic pitch propeller

2017 11th Asian Control Conference (ASCC), 2017
This paper aims to develop an optimal state feedback controller using the Linear Quadratic Regulator for an autonomous underwater vehicle equipped with an innovative collective and cyclic pitch propeller. This new type of propulsion system offers advantages such as good manoeuvrability for the torpedo shaped underwater vehicle at low speed operations ...

Performance and control of a collective and cyclic pitch propeller for an underwater vehicle

2023
Most of the underwater vehicles have control surfaces to enable manoeuvring. The problem with an underwater vehicle with control surfaces is operating it at low speed. At low speed, the control surfaces become inoperative as the magnitude of the generated lift relates to the water speed passing over the control surfaces.

Blade Pitch Control for Floating Wind Turbines via Event-Triggered Model-Free Adaptive Control Strategy

IEEE Transactions on Automation Science and Engineering
It is difficult to obtain an accurate mechanism model of a floating wind turbine due to the large coupling disturbance of wind and wave at sea, and the control accuracy is difficult to guarantee, so maintaining stable power output is a challenge ...
