Abstract
A method is disclosed for adjusting a proportional, integral, derivative controller in a limited rotation motor system. The method includes the step of providing a first frequency domain sequence that is representative of a frequency domain representation of a motor control signal responsive to a first digital signal that is representative of the motor control signal. The method also includes the step of providing a second frequency domain sequence that is representative of a frequency domain representation of a position detection signal responsive to a second digital signal that is representative of the position detection signal. The method further includes the steps of identifying a representation of a ratio of the first and second frequency domain sequences, and identifying appropriate values for the coefficient k.sub.p of a proportional unit of the system, for the coefficient k.sub.i of an integral unit for the system, and for the coefficient k.sub.d of a derivative unit for the system responsive to the ratio of the first and second frequency domain signals.
