A noise canceling system includes a signal generator module that generates
a set point signal based on a desired position signal and a position
feedback signal, a summation module that generates an output control
signal based on the set point signal and a correction signal, and a
filter module that generates the correction signal based on a disturbance
signal and that minimizes a correlation between the disturbance signal
and an error signal. The error signal represents a difference between the
desired position signal and the position feedback signal.
