Modulating operator input for work element actuator operation

A computer-implemented method for controlling movement of a work element of a power machine, the method comprising:

• receiving, from an operator input device, an actuation command signal for commanded movement of an actuator of the work element, wherein the actuation command signal is based on a physical movement of the operator input device, wherein vibration from operation of the power machine induces at least a portion of the physical movement of the operator input device;
• filtering the actuation command signal to generate a filtered actuation command signal, wherein filtering the actuation command signal attenuates a frequency component of the actuation command signal that corresponds to a vibrational resonant frequency of the power machine;
• and
• causing the actuator of the work element to move based on the filtered actuation command signal.

A power machine comprising:

• a main frame;
• a work element supported by the main frame, the work element comprising:
• a lift arm moveably secured to the main frame;
• an implement carrier movably secured to the lift arm;
• and
• an actuator that is configured to move the implement carrier with respect to the lift arm, or the lift arm with respect to the main frame;
• an operator input device that is configured to transmit actuation command signals based on operator input that commands movement of the implement carrier, to control the actuator of the work element to cause movement of the implement carrier that corresponds to the commanded movement;
• a control system that includes a control device in communication with the operator input device and the actuator, the control device being configured to:
• in response to movement of the operator input device by an operator, receive, from the operator input device, an actuation command signal that commands movement of the actuator, wherein a portion of the movement of the operator input device is induced by operational vibration of the power machine, and wherein the actuation command signal includes a vibrational component corresponding to the portion of the movement;
• and
• control the actuator for movement of the implement carrier based on the movement of the operator input device by the operator, including, for a first frequency range of the actuation command signal, filtering the actuation command signal using a band-stop filter to generate a filtered actuation command signal that excludes at least a portion of the actuation command signal received from the operator input device.
