description A prime mover (22) and a plurality of hydraulic actuators (6), a hydraulic machine (32) having a rotatable shaft in driven engagement with the prime mover and comprising a plurality of working chambers, a hydraulic circuit extending between a group of one or more working chambers of the hydraulic machine and one or more of the hydraulic actuators, each working chamber of the hydraulic machine comprising a low-pressure valve (52) which regulates the flow of hydraulic fluid between the working chamber and a low-pressure manifold and a high-pressure valve (64) which regulates the flow of hydraulic fluid between the working chamber and a high-pressure manifold. The hydraulic machine being configured to actively control at least the low-pressure valves of the group of one or more working chambers to select the net displacement of hydraulic fluid by each working chamber on each cycle of working chamber volume, and thereby the net displacement of hydraulic fluid by the group of one or more working chambers, responsive to a demand signal, wherein the apparatus further comprises a controller (26) configured to calculate the demand signal in response to a measured property of the hydraulic circuit or one or more actuators.
