Abstract :� � This paper deals with nonlinear dynamic systems with and without given boundary conditions on control inputs while�considering objective function as a minimum jerk. However, the comparison with a minimum energy has been done in order to
show some advantage and disadvantage between minimum energy and minimum jerk while considering the problem with�given boundary conditions on control inputs. The solutions show that the nonlinear problem chosen as example here in this�paper has the same solution from both minimum energy and minimum jerk while given boundary constraints on control inputs.�Moreover, the problems with given boundary conditions on control input have less cost if the energy is considered as an�objective function.
