Under-actuated Machine Control
Offshore floating wind turbine exhibits plastic vibration for power generation. The similar vibration happens to the oscillating screen machine, commonly seen in the power plant’s coal preparation process. They are under-actuated phenomena. Analyzing the under-actuated mechanism, we developed under-actuated TORA (translational oscillator with rotational actuator) system to stabilize the oscillation of offshore wind turbine and solve the oscillating screen machine’s flexible control problems.
