| 英文摘要 |
| For a class of switched non-strict feedback nonlinear systems with measurable output only at the sampling
points, this paper presents an adaptive output feedback control design method based on a fuzzy sampling observer. The
given method reduces the conservation of the existing results led to by common control thoughts under arbitrary switching.
Both the“explosion of complexity”problem resulting from the repeated differentiation for the virtual controls during the
iterative process and high gain phenomenon of the constructed common controller are avoided in this paper. The designed
switched adaptive laws highlight the characteristic of each switched subsystem. Information transmission resources can be
saved by the constructed controller depending on sampling data. The common Lyapunov function theory ensures that all
variables of the corresponding closed-loop switched systems are uniformly bounded under arbitrary switching. |
