主 题:optimal control problem hysteresis biological diffusion models nonconvex integrands nonconvex control constraints
摘 要:This paper addresses a nonlinear partial differential control system arising in population *** system consist of three diffusion equations describing the evolutions of three biological species:prey,predator,and food for the prey or *** equation for the food density incorporates a hysteresis operator of generalized stop type accounting for underlying hysteresis effects occurring in the dynamical *** study the problem of minimization of a given integral cost functional over solutions of the above *** set-valued mapping defining the control constraint is state-dependent and its values are nonconvex as is the cost integrand as a function of the control *** relaxationtype results for the minimization problem are obtained and the existence of a nearly optimal solution is established.
