CONTROLLER FOR HYDRAULIC APPARATUS
The present invention provides a controller for hydraulic apparatus (100). The controller is configured to determine (310) that an energy return criteria has been met by movement of a first movement component of a first hydraulic actuator. In response thereto, the controller is further configured to...

| description | The present invention provides a controller for hydraulic apparatus (100). The controller is configured to determine (310) that an energy return criteria has been met by movement of a first movement component of a first hydraulic actuator. In response thereto, the controller is further configured to select (320) at least one among a plurality of energy control strategies based on at least one operational characteristic of the hydraulic apparatus, and to control (330) the hydraulic apparatus to implement the energy control strategy during movement of the first movable component in such a way as to meet the energy return criteria. The plurality of energy control strategies comprises a first energy control strategy and a second energy control strategy. The at least one operational characteristic of the hydraulic apparatus comprises an indication of an expected energy recovery of one or more of the energy control strategies. The first energy control strategy comprises transferring energy from the first hydraulic actuator, via a hydraulic machine, to an energy consumer in torque connection with the hydraulic machine. The second energy control strategy comprises transferring energy from the first hydraulic actuator to a low-pressure reservoir of hydraulic fluid in the hydraulic circuit. |
