Subordination of Predictable Compensators

1 Subordination at the Interface : the Quasi - Subordination Hypothesis

The subordination of clauses, and the recursion which results, lies at the heart of linguistic representation. Yet there are many aspects of subordination that are not fully understood. An enduring puzzle is that some clauses which appear to be structurally subordinate nevertheless pattern with main clauses in certain, but not all, respects. This paper posits that such clauses, which we term “q...

Subordination by convex functions

Robust synthesis of feedforward compensators

The design of a feedforward compensator for robust H1 or H2 performance under structured uncertainty is considered. For linear time-invariant uncertainty, a convex method based on linear matrix inequalities (LMI’s) across the frequency variable is given. For nonlinear or time-varying perturbations and H1 performance, the design problem is reduced exactly to a state-space LMI, and extensions to ...

Fuzzy Differential Subordination

The method of differential subordination or ”admissible functions method” was introduced by P.T. Mocanu and S.S. Miller in [1], [2] and then developed in monography [3], as well as in other papers of other mathematicians. Until now, the notion of differential subordination appears in papers published in various journals specialized in complex analysis around the world. We extend this method to ...

Frequency - Shaping with Spatial Compensators

Practical realizations of adaptive structures should be designed and implemented to maximize performance, robustness and efficiency. A method of frequency-shaping the compensation of an adaptive structure is developed for increased performance, system robustness and efficiency. Robustness is defined as reduced coupling to out-of-bandwidth modes, where model fidelity frequently suffers, and to i...
