Abstract
Various illustrative aspects are directed to a system comprising: an actuator; a control object, controlled by the actuator; and one or more processing devices, configured to perform positioning control of the control object via the actuator, wherein performing the positioning control comprises: generating a trajectory control signal for a trajectory that comprises a polydyne acceleration ramp; and outputting the trajectory control signal to the actuator.
Claims20
A system comprising:
- an actuator;
- a control object, controlled by the actuator;
- and
- one or more processing devices, configured to perform positioning control of the control object via the actuator, wherein performing the positioning control comprises:
- generating a trajectory control signal for a trajectory that comprises a polydyne acceleration ramp configured to suppress at least one resonant mode;
- and
- outputting the trajectory control signal to the actuator.
4 more elements
A method comprising:
- generating, by one or more processing devices, a trajectory control signal for a trajectory that comprises a polydyne acceleration ramp configured to suppress at least one resonant mode;
- and
- outputting, by the one or more processing devices, the trajectory control signal to an actuator that controls a control object.
One or more processing devices comprising:
- means for generating a trajectory control signal for a trajectory that comprises a polydyne acceleration ramp configured to suppress at least one resonant mode;
- and
- means for outputting the trajectory control signal to an actuator that controls a control object.
