Fast Parameter Learning in Adaptive Systems
Adaptive control pertains to the control of dynamic systems exposed to parametric uncertainties in real-time with guarantees of stability and control goals of tracking. A central part of adaptive control is parameter estimation. Real-time adaptive control requires parameter estimation to occur …

Analysis of slow convergence regions in adaptive systems
… properties of errors are examined in a class of adaptive systems that corresponds to adaptive control of linear time-invariant plants with state variables accessible. The existence of a sticking region is demonstrated in the error space where the state errors move with a finite velocity …

A Complex Adaptive Systems Analysis of Productive Efficiency
Linkages between Complex Adaptive Systems (CAS) thinking and efficiency analysis remain in their infancy. This research associates the basic building blocks of the CAS 'flocking' metaphor with the essential building block concepts of Data Envelopment Analysis (DEA). Within a proposed framework DEA …
