BOUNDARY CONTROLLABILITY OF NONLINEAR STOCHASTIC FRACTIONAL SYSTEMS IN HILBERT SPACES

摘要

Sufficient conditions for the controllability of nonlinear stochastic fractional boundary control systems are established. The equivalent integral equations are derived for both linear and nonlinear systems, and the control function is given in terms of the pseudoinverse operator. The Banach contraction mapping theorem is used to obtain the result. A controllability result for nonlinear stochastic fractional integrodifferential systems is also attained. Examples are included to illustrate the theory.
