Interval observer-based finite-time control for linear parameter-varying systems

作者:

Highlights:

• An unknown input observer framework is utilized to construct the interval observer to avoid the cooperativity constraint in estimation error dynamics.

• The corresponding control scheme composed of upper-lower bounds of the controller is established to treat the time-varying parameter in control input channel.

• Sufficient conditions are formulated as LMIs to guarantee the finite-time boundedness of error systems.
