Abstrakt: This paper presents extensions of the model free subspace based ℋ︁∞control approach. In particular, a fast algorithm for computing a subspace predictor from experimental data is introduced. The paper also describes a fast algorithm for updating the subspace predictor when new experimental data are available. These algorithms can be applied in conjunction with model free subspace based ℋ︁∞control in order to create a novel adaptive control law. A defining feature of this control law is that an estimate of achievable performance is maintained throughout the operation of the closed‐loop system. These algorithms are used to demonstrate the closed‐loop control of a flexible structure. Copyright © 2001 John Wiley & Sons, Ltd.
