Abstract

In this chapter one considers a Youla–Kučera parametrization of the feedforward compensator in the context of the “positive” feedback coupling which appears in active vibration control systems. The central Youla–Kučera controller will stabilize the internal “positive” feedback loop and an infinite (or finite) impulse response adaptive Youla–Kučera filter will be used to optimize the performance. The algorithms are evaluated in real time on the active flexible mechanical structure actuated by an inertial actuator which has been presented in Chap. 2.

Fußnoten
1
In adaptive control and estimation the predicted output at \(t+1\) can be computed either on the basis of the previous parameter estimates (a priori) or on the basis of the current parameter estimates (a posteriori).
 
2
The parenthesis \((q^{-1})\) or \((z^{-1})\) will be omitted in some of the following equations to make them more compact.
 
3
Nevertheless, exact algorithms can be developed taking into account the non-commutativity of the time-varying operators—see [3].
 
4
One cannot use in practice Algorithm I as the true model of the secondary path is not known. Instead one can use Algorithm II with an estimation of the secondary path model.
 
5
Convergence analysis in a stochastic environment can be applied only for vanishing adaptation gains.
 
6
An array implementation as in [8] can be also considered.
 
7
The orders of the initial H\(_\infty \) controller were: \(n_{R_{H_\infty }} = 70\) and \(n_{S_{H_\infty }} = 70\).
