摘要
A feedback control system provides an adjusted command signal to a plant in response to a command signal having a plurality of command signal components. The plant controls a subsystem and provides a feedback signal representative of the subsystem's achieved response to the adjusted command signal. An adaptive filter adjusts the amplitude and phase of relatively high frequency command signal components in accordance with a dynamic behavior of the adaptive filter. A compensation device adjusts a dynamic behavior of the adaptive filter in response to the feedback signal and the adjusted command signal. In one form of the invention, a low-pass filter passes command signal components of relatively low frequency, and a summing element generates the adjusted command signal in response to the output from the adaptive filter and the command signal components passed by the low-pass filter. In another form of the invention, a spectral preemphasis filter increases the power of the signal components of the feedback signal and the adjusted command signal in proportion to the frequency of the signal components.
