This system is modeled as a parabolic partial differential equation (PDE) and is only powered from one boundary with a Dirichlet type of actuator. By taking the Volterra integral transformation, we obtain a nominal PDE with asymptotic This variation permits flexibility and survival of a population in the face of changing environmental circumstances.

Given a prespecified sequence of active subsystems, the objective is to seek both the continuous control input and the discrete switching instants that minimize a performance index over a finite time horizon. Based on the use of the calculus of variations, necessary A reader familiar with the classical theory of optimal control and the calculus of variations might think that the most natural approach to the solution of these problems is to use rst-order necessary conditions to for-mulate and solve a two-point-boundary-value problem.
