High-order techniques have been proposed for obtaining high accuracy and rapid convergence in numerical solutions of integral equations for electromagnetics. Results obtained for structures with smooth surfaces exhibit relatively low errors, and the rate of decrease in the error improves with reduced cell sizes as either the basis function or the representation order increases. Recent publications...
This short paper will address the problem of consistent parameter estimation in adaptive regulation and adaptive control for multivariable, deterministic systems. The parameter estimators considered here are the RLS estimator and the RLS estimator with covariance resetting. A decaying excitation technique, which is similar to that given in (2), will be used to ensure consistent parameter estimation...
Procedures that are efficient in classical manual computing techniques are frequently inefficient for use on digital computers; for example, as pointed out by Polak, the Nyquist criterion we have had for years turns out to be quite incompatible in CAD. Similarly, the Evans root locus method is not quite compatible with modern design technique either, when we examine it carefully from the CAD point...
