摘要： Regeneration control is exercised and energy saving is realized even when an abnormality occurs to pressure sensors for hydraulic actuators. A work machine includes: a hydraulic pump (41b) that supplies a hydraulic fluid to a second hydraulic actuator (34); a regeneration circuit (47) that regenerates a return hydraulic fluid from a first hydraulic actuator (32) between the second hydraulic actuator (41b) and the hydraulic pump (41b); a discharge circuit (46) that discharges the return hydraulic fluid from the first hydraulic actuator (32) to a tank; a regeneration amount regulation device (45) that regulates a proportion of a flow rate of the return hydraulic fluid flowing to the regeneration circuit (47) and a flow rate of the return hydraulic fluid flowing to the discharge circuit (46); a controller (100) that controls the regeneration amount regulation device (45); a first operation amount sensor (53a) that detects an operation amount of the first operation device (51); and a first hydraulic actuator speed computing unit (111) that computes a speed of the first hydraulic actuator (32). The controller (111) controls the regeneration amount regulation device on the basis of the operation amount detected by the first operation amount sensor (53a) and the speed computed by the first hydraulic actuator speed computing unit (111).

摘要： A method and system that compensates for kinematic accelerations influencing a sensor measurement of working equipment such as an excavator. The method and system identify members of the working equipment that are movable relative to each other (e.g. stick, boom, bucket) and define a co-ordinate frame for each movable member. A kinematic relationship, preferably a kinematic chain. The sensor measurement is then modified according to the kinematic relationships and the relative position of each identified member.
