Adaptive Dynamic Surface Decentralized Output Feedback Control for Switched Nonstrict Feedback Large-Scale Systems with Unknown Dead Zones

الملخص EN

This paper investigates a novel adaptive output feedback decentralized control scheme for switched nonstrict feedback large-scale systems with unknown dead zones.

A decentralized linear state observer is designed to estimate the unmeasurable states of subsystems.

The dead zone inverse technique is used to compensate the effect of the unknown dead zone.

A variable separation approach is applied to deal with the nonstrict feedback problem.

Moreover, dynamic surface control and minimal parameter learning technology are adopted to reduce the computation burden.

The proof of stability and the arbitrary switching are obtained by the common Lyapunov method.

Finally, simulation results are given to show the effectiveness of the proposed control scheme.
