Classical methods are not usually efficient, to solving nonlinear control problems and especially Nonlinear distributed parameter systems Optimal Control Problems (NOCP). In this paper we introduce a new approach for solving this class of problems by using NonLinear Programming Problem (NLPP). First, we transfer the original problem to a new problem in form of calculus of variations. The next step we discrete the new problem and solve it by using NLPP packages. Moreover, a NLPP is transferred to a Linear Programming Problem (LPP) which empowers us to use powerful LP software. Finally, efficiency of our approach is confirmed by some numerical examples.

Keywords: optimal control, distributed parameter systems, calculus of variations, nonlinear programming
