The papers in this volume were delivered at a workshop held to celebrate the 60th birthday of Professor Petar V. Kokovich. All the papers were deliverd by former students of Professor Kokovich and cover a wide variety of topics in control and applications. These topics include: using sensitivity methods to design an adaptive controller for automotive speed control; advances in adaptive nonlinear control; hardware implementation schemes for fuzzy control systems; algorithms for modelling and an analysis of a hybrid system; the role of manifolds in system reduction and feedback designs which exploit time-scale separation; applying sample-data techniques to nonlinear singularly perturbed systems; a nonlinear model reduction formulation for large power systems based on slow coherency; and aggregation ideas.
