Abstract

Adaptive output feedback control algorithm providing exact tuning of adjustable parameters to unknown values which ensure desired bifurcation properties of the system is proposed. Design of the algorithm is based on passification and adaptive observer. Application examples like neural integrator, resonant pendulum and three dimensional oscillator, are presented and illustrated by simulation results.
