Abstract: A method for determining a capacitance value of a capacitor is provided. The method includes receiving a current signal flowing through the capacitor and receiving a voltage signal applied across the capacitor. The received voltage signal and the received current signal are filtered with a low pass filter. The filtered voltage signal and the filtered current signal are then discretized. The discretized voltage signal and the discretized current signal are transformed into a frequency domain. The capacitance value of the capacitor is determined from the transformed voltage signal and the transformed current signal.

Abstract: A hydraulic system includes a hydraulic pump and a motor configured to drive the hydraulic pump. A sensor measures motor speed. A controller includes a model configured to determine system parameters based on the measured motor speed, and the controller is configured to output control signals to the motor and a fan based on the determined system parameters.
