Abstract:
A hydraulic system and a method comprising a linear actuator  23  for generating discrete sum forces, chambers A-D for generating discrete force components, at least two charging circuits  3,4  configured to maintain predetermined pressure levels of hydraulic fluid, independent control interfaces  9 - 16  configured to open and close connections of the first and second charging circuits to the chambers, and an electronic control unit  50  for controlling the control interfaces. At least two control interfaces are proportional valves which are used as shut-off valves and are independently switchable to the open and closed positions in a controlled manner. Moreover, non-throttled control and secondary control are implemented in the hydraulic system and the method.

Claim (Index 12):
A method for controlling a hydraulic system, the hydraulic system comprising:\n a linear actuator for generating several discrete sum forces of different magnitudes; at least four chambers provided in the linear actuator and generating several discrete force components whose combinations generate said sum forces; at least two charging circuits for maintaining predetermined pressure levels of hydraulic fluid, particularly the first pressure level of the first charging circuit and the second pressure level of the second charging circuit; as well as for supplying hydraulic fluid to the linear actuator and receiving hydraulic fluid from the linear actuator; several independent control interfaces for opening and closing connections of the first and second charging circuits to the chambers; including at least\n a first control interface for opening and closing the connection of the first charging circuit to the first chamber; and \n a second control interface for opening and closing the connection of the second charging circuit to the first chamber; \n an electronic control unit for controlling at least two control interfaces, including at least the first and the second control interfaces; in which method at least two control interfaces, including the first and the second control interfaces, are proportional valves which are used as shut-off valves and are independently shiftable to the open and closed positions in a controlled manner.
