Robust adaptive control of dynamic hybrid systems

This paper deals with the problem of synthesizing a robust adaptive controller for a class of single-input single-output time-invariant hybrid plant which can operate under bounded disturbances and / or unmodelled dynamics. The hybrid plant dealt with is composed of two subsystems one being of continuous-time type while the other is digital. The system is simultaneously driven by the standard continuous-time input plus an extra signal. A relative adaptation dead zone is used in the parameter estimation scheme whose role is the robust adaptive stabilization in the presence of uncertainties.
