Harmonic Cancellation is available for the A3200 Software-Based Machine Controller, the Ensemble Stand-Alone Multi-Axis Motion Controller and the Soloist Stand-Alone Single-Axis Motion Controller.
Optimize Periodic Trajectories
Aerotech’s Harmonic Cancellation algorithm dramatically reduces positioning errors on systems with periodic trajectory commands. Part of Aerotech’s Dynamic Controls Toolbox, it is simple to experience enhanced performance enabled by Harmonic Cancellation.
With Harmonic Cancellation, a set of controller-level algorithms improve performance by reducing tracking error caused by:
- Sinusoidal reference commands
- Motor force ripple
- Other position-dependent disturbances
- Cross-axis disturbances (such as that created on a linear axis carrying an unbalanced rotational axis)
