THE INVARIANCE OF APPROXIMATE REACHABLE SET FOR DISTRIBUTED PARAMETER CONTROL SYSTEM UNDER NONLINEAR PERTURBATION
分布参数控制系统逼近能达集对非线性扰动的不变性

In this paper we consider the invariance of approximate reachable set for abstract lineardistributed parameter control system under nonlinear perturbation,and give the sufficientconditions.These results could imply the approximate contrallability of a nonlinear distribut-ed parameter control system.
