Maximally Robust Controllers for Multivariable

The set of all optimal controllers which maximize a robust stability radius for unstructured additive perturbations may be obtained using standard Hankel-norm approximation methods. These controllers guarantee robust stability for all perturbations which lie inside an open ball in the uncertainty space (say, of radius r1). Necessary and sufficient conditions are obtained for a perturbation lyin...

A QFT/EEAS Design of Multivariable Robust Adaptive Controllers

This paper presents a robust adaptive control design methodology for multi-input multi-output (MIMO) plants based on Quantitative Feedback Theory (QFT) and Externally Excited Adaptive System (EEAS), both of which are the novel ideas of Horowitz. Self Oscillating Adaptive Systems (SOAS) are proposed to mainly overcome the problem of large gain variations, which is important in certain applicatio...

Gain Bounds for Switched Adaptive Controllers

A class of discrete plants controlled by a switching adaptive strategy is considered, and lp bounds, 1 ≤ p ≤ ∞, are obtained for the closed loop gain relating input and output disturbances to internal signals.

A Unified Approach to High-Gain Adaptive Controllers

and Applied Analysis 3 Subsequently, various authors 1, 5, 6, 10 assumed that the output is obtained via sampleand-hold, that is, yi : y ti with ki : k ti and i ∈ N0. Thus it becomes necessary also to adapt the sample period hi : ti 1 − ti, so the closed-loop control objectives are yi ∈ 2 i0,∞ , lim i→∞ ki < ∞, lim i→∞ hi > 0. 2.6 Though several variations on these results exist, these remain t...

A New Approach for QFT-type Robust Controller Design in Uncertain Multivariable Systems

This paper presents a robust controller design methodology for a class of linear uncertain multivariable systems with hard time-domain constraints on their outputs and control signals in response to step disturbance inputs. In this approach, the m×m MIMO system is replaced by m2 SISO systems and then, using the QFT technique, desirable controllers are synthesized. The final controller will be d...
