Frequency domain iterative tuning for the control of nonlinear vibrations
Frequency domain iterative tuning for the control of nonlinear vibrations
A general gradient estimation method is proposed
that relies on the computation of system dynamics and signals
in the frequency domain. With the theory presented the
computation of the gradient of an average linear quadratic (LQ)
performance criterion can be simplified using only ‘partialmodelling’
with respect a finite signals spectrum. Using gradient
estimate a new iterative tuning (IT) method is presented
for nonlinear Active Noise and Vibration Control (ANVC)
problems. The most important novelty of the method is that it
performs one experiment per iteration that makes it suitable
for implementation as a self-tuning and adaptive controller.
Apart from the reduced number of experiments, relative to
time domain IFT methods, the new method has the added
advantage of its suitability for enhanced disturbance rejection
tuning in the frequency domain. The effectiveness of the method
is demonstrated on physical laboratory hardware.

Abstract
A general gradient estimation method is proposed
that relies on the computation of system dynamics and signals
in the frequency domain. With the theory presented the
computation of the gradient of an average linear quadratic (LQ)
performance criterion can be simplified using only ‘partialmodelling’
with respect a finite signals spectrum. Using gradient
estimate a new iterative tuning (IT) method is presented
for nonlinear Active Noise and Vibration Control (ANVC)
problems. The most important novelty of the method is that it
performs one experiment per iteration that makes it suitable
for implementation as a self-tuning and adaptive controller.
Apart from the reduced number of experiments, relative to
time domain IFT methods, the new method has the added
advantage of its suitability for enhanced disturbance rejection
tuning in the frequency domain. The effectiveness of the method
is demonstrated on physical laboratory hardware.
