AN APPLICATION OF DIFFERENTIAL TRANSFORMATION FOR OPTIMAL CONTROL OF NONLINEAR PROCESSES
Abstract:
In paper, the differential transformation is applied for solving problems of nonlinear optimal
control processes by dynamic objects. An approach based on the multi-step differential transform method
and the Adomian polynomials for approximation of nonlinear terms of differential equations that describe
dynamic process is proposed. It is offered an optimization model of multi-step control process. The model
advantage is the possibility of process simulation of optimal control with piecewise continuous functions,
determination of an optimal control and state trajectories without using numerical integration methods of
differential equations of object dynamics. Herewith, the analytical solution of a problem is allowed, which
essentially reducing amount of calculation.
