Abstract
This study proposes a nonlinear adaptive control design using backstepping approach for output feedback type nonlinear control systems with unknown constant parameters. A class of nonlinear systems with parameter uncertainties and with some unmeasured states is of interest for nonlinear adaptive control. The proposed control design uses the control Lyapunov functions to maintain the stability of the control system and makes the parameter adaptation using tuning functions. One of the aim of this study is to prove the applicability of the proposed adaptive control design approach to the real control systems. For this aim, an active magnetic bearing system is used for experimental verification. The obtained results are encouraging for future studies.
