Unfalsified adaptive control with reset and bumpless transfer

Adaptive switching control for time-varying plants based on the Battistelli-Hespanha-Mosca-Tesi reset mechanism is investigated. A new reset mechanism is designed and the switching algorithm is improved to admit bumpless transfer at switching times, and to relax several restrictive assumptions. Stability is proved given only that the adaptive stabilization problem is feasible, removing the assumption that the plant is linear and relaxing restrictions on controller state-initialization at switching times so as to allow bumpless transfer. An example is provided to support improved results.
