This operator can be used to cancel out load sway induced by speed changes in one motion axis. This operator does not dampen dynamic sway induced by external forces.
Arguments
| Name | Description |
|---|---|
| SpeedIn | Input speed request. |
| SpeedOut | Anti-Sway ramped speed request. |
| CableLength | Effective length of load cable. |
| DampeningFactor | Estimate of fraction of load sway amplitude loss per period. |
| StopPosition | Estimated position of full stop based on position, current speed, speed change requests and remainder of velocity to full stop. |
| Position | Current position. Used for StopPosition estimatition. |
| MaxChangeRate | Maximum rate of change allowed for speed in the system. Used for StopPosition estimatition. |
Example
Below is an example plot with SpeedIn up ramp and down ramp with SpeedOut, Position and StopPosition estimate plotted as a reference for the operator behavior.
