Abstract
This disclosure describes systems, methods, and apparatus for generating a control signal for one or more actuators that is adjusted from a control signal dictated by setpoints, where the adjustment accounts for predicted delays and amplitude errors. More specifically, cross correlation between measurements of the actuator(s) outputs and time-shifted setpoints can be optimized for a time-shift that minimizes the cross correlation. The time-shifted setpoints along with the measurements can then be used to determine an amplitude difference and to remove noise from the amplitude difference. Dynamic uncertainty can then be found from this denoised data set and further optionally used to find the noise that was removed. The time delay, noise, and dynamic uncertainty can be used to preemptively adjust the control signal.
