Abstract
Collective control using vertical velocity is provided. A system can include a data processing system comprising one or more processors, coupled with memory. The data processing system can receive, from a sensor, a velocity of an aerial vehicle along a vertical axis of a body of the aerial vehicle. The data processing system can generate a command for collective control of a pitch of blades of a rotor of the aerial vehicle based on a comparison of the velocity with a reference. The data processing system can control, via an actuator, the pitch of the blades of the rotor in accordance with the command.
Claims20
A system, comprising:
- a data processing system comprising one or more processors, coupled with memory, to:
- receive, from a sensor, a velocity of an aerial vehicle along a vertical axis of a body of the aerial vehicle;
- generate a command for collective control of a pitch of blades of a rotor of the aerial vehicle based on a comparison of the velocity with a reference;
- and
- control, via an actuator, the pitch of the blades of the rotor in accordance with the command.
A method, comprising:
- receiving, by a data processing system comprising one or more processors, coupled with memory from a sensor, a velocity of an aerial vehicle along a vertical axis of a body of the aerial vehicle;
- generating, by the data processing system, a command for collective control of a pitch of blades of a rotor of the aerial vehicle based on a comparison of the velocity with a reference;
- and
- controlling, by the data processing system, an actuator to change the pitch of the blades of the rotor in accordance with the command.
A rotorcraft, comprising:
- processing circuitry to:
- receive, from a sensor, a velocity of the rotorcraft along a vertical axis of a body of the rotorcraft;
- generate a command for collective control of a pitch of blades of a rotor of the rotorcraft based on a comparison of the velocity with a reference;
- and
- control, via an actuator, the pitch of the blades of the rotor in accordance with the command.
