Active compensation system, suitable to compensate at least partially for the effect of an undulating movement on a load,
- which active compensation system (1) comprises:
- electrical motor means (2), suitable for maneuvering said load during a first phase (A) of said undulating movement,
- electrical power supply means (3), electrically connected to the electrical motor means (2), for electrically powering said electrical motor means (2),
- electrical storage means (4), electrically connected to the electrical motor means (2), to complete the electrical supply of said electrical motor means (2) during said first phase (A) of the undulating movement,
- control means (5) that controls said active compensation system (1),
- wherein said electrical supply means (3) are also electrically connected to the electrical storage means (4), to electrically power said electrical storage means (4),
- which active compensation system (1) further comprises electrical energy dissipating means (6) which are electrically connected to the electrical motor means (2), the electrical energy dissipating means (6) converting the electrical energy produced by the said electrical motor means (2) during a second phase (B) of said undulating movement into heat energy,
- and which control means (5) comprise a piloting module (51) designed to:
- discharge said electrical storage means (4) during said first phase (A) of the undulating movement, to participate in the electrical supply of said electrical motor means (2) in addition to said electrical supply means (3), and
- recharge said electrical storage means (4) via said electrical supply means (3), during said second phase (B) of the undulating movement,
- wherein the electrical energy restored by the electrical motor means (2) during the second phase (B) of said undulating movement is taken over by the electrical energy dissipating means (6), without being stored in the electrical storage means (4), and
- wherein the electrical energy dissipating means (6) consist of braking resistor means.
