Elleuch Dorsaf, Damak Tarak . Article:Combined Adaptive Observer-Controller for Lipschitz Nonlinear Systems. International Journal of Computer Applications. 32, 5 ( October 2011), 38-47. DOI=10.5120/3902-5469
A combination between an adaptive sliding mode observer and a backstepping sliding mode controller is designed for a Lipschitz nonlinear system. This combination guaranties the tracking of trajectory, estimation of both the unmeasured state and the unknown parameters. A parameter variation margin is defined for that the combination is robust. The simulation results prove the combination robustness when the parameters are constants or varied in a defined margin.
