Abstract
In some implementations, a hydraulic system may include a tank, a hydraulic pump, an actuator, and an unloading valve positioned between the pump and the tank. The hydraulic system may receive one or more inputs associated with the hydraulic system. The hydraulic system may determine, based on the one or more inputs, one or more desired system pressures associated with the hydraulic system. The hydraulic system may proportionally regulate an opening of the unloading valve to operate the hydraulic system at the one or more desired system pressures.
