摘要： A hydraulic power control system for a work machine is provided. The system may include a hydraulic power output device selected from the group consisting of a hydraulic motor and a work implement hydraulic actuator. The system may also include a variable displacement hydraulic pump configured to supply hydraulic fluid to the hydraulic power output device. The system may further include at least one pressure sensor configured to measure pressure of the hydraulic fluid at a location between the pump and the hydraulic power output device. In addition, the system may include at least one temperature sensor configured to measure a temperature of the hydraulic fluid in the system. The system may include a controller configured to control a displacement of the pump based on a pressure measurement of the at least one pressure sensor and a temperature measurement of the at least one temperature sensor.

摘要： The present invention provides apparatuses and methods for filtering a signal. A first processing device receives a first control signal and a first feedback signal and transmits a first error signal as a function of those signals. A second processing device receives the first error signal and transmits a second control signal as a function of the first error signal, a deadband, and a gain factor. A third processing device receives the second control signal and the first feedback signal and transmits an output signal as a function of those signals. A fourth processing device receives the output signal and transmits the first feedback signal as a function of the output signal to the first processing device and the third processing device, the first feedback signal being substantially equal to the output signal delayed by a first predetermined duration of time.
