Systems and methods for vibration attenuation in flight control of an aircraft

An aircraft, comprising:

• at least two propellers;
• at least one processor configured to:
• receive pilot input indicating a commanded aircraft state;
• determine an aircraft thrust for achieving the commanded aircraft state;
• determine a difference in speed between the at least two propellers that reduces a structural vibratory response in the aircraft;
• determine a respective command for each propeller of the aircraft to achieve the determined aircraft thrust while also meeting the determined speed difference;
• and
• control each propeller of the aircraft based on the corresponding respective command.

A method for controlling an aircraft, comprising:

• receiving, using at least one hardware processor, pilot input indicating a commanded aircraft state;
• determining, using the at least one hardware processor, an aircraft thrust for achieving the commanded aircraft state;
• determining, using the at least one hardware processor, a difference in speed between at least two propellers that reduces a structural vibratory response in the aircraft;
• determining, using the at least one hardware processor, a respective command for each propeller of the aircraft to achieve the determined aircraft thrust while also meeting the determined speed difference;
• and
• controlling, using the at least one hardware processor, each propeller of the aircraft based on the corresponding respective command.

An electrical system for an aircraft, comprising:

• at least one processor configured to execute instructions to cause the system to:
• receive pilot input indicating a commanded aircraft state;
• determine an aircraft thrust for achieving the commanded aircraft state;
• determine a standard deviation in propeller speed across propellers of the aircraft that reduces a structural vibratory response in the aircraft;
• determine a respective command for each propeller of the aircraft to achieve the determined aircraft thrust while also meeting the standard deviation in propeller speed;
• and
• control each propeller of the aircraft based on the corresponding respective command.
