FEEDFORWARD CONTROL METHOD FOR OSCILLATION OR THE LIKE OF FLOATING MATTER USING INCIDENT WAVE SIGNAL

PURPOSE:To control properly the oscillations of a fixed matter or a floating matter by detecting an incident wave signal at the front of a matter set at the wave incident side and using the detected incident wave signal to change the parameter of an external dynamic system. CONSTITUTION:For a wave a...

Zusammenfassung:	PURPOSE:To control properly the oscillations of a fixed matter or a floating matter by detecting an incident wave signal at the front of a matter set at the wave incident side and using the detected incident wave signal to change the parameter of an external dynamic system. CONSTITUTION:For a wave absorbing energy device E, an air pass port 3 is formed at the upper part of a fixed matter 1 set on waves together with a variable nozzle 2 and a duct 4 set at the lower and upper end parts of the port 3 respectively. A Wales turbine 5 is provided within the duct 4, and the power of the turbine 5 is transmitted to an energy absorber main body G of a generator 8, etc. via a belt 7, etc. In addition, a detection device such as a wave motion measurement device, etc. is provided to the device E at the front of a matter set at the wave incident side. The detection value of said detection device undergoes the arithmetic processing through an arithmetic device to control the size of a variable nozzle 2 as well as the capacity value of a variable capacitor of an electric circuit. Thus the flowing speed of the air passing through the turbine 5 is kept at an optimum state. At the same time, the revolutions of the generator 8 are changed to obtain synchronization with a wave cycle to obtain the highest absorption efficiency of energy.
