Abstract: In this paper, an on-board optimal control problem for diesel engines with lean NOx trap (LNT) is investigated. First, a two-order LNT model based on mass conservation and energy conservation is constructed. Then, the optimal control problem is formulated as a continuous receding horizon problem under dynamical model constraint and descretized into a nonlinear programming problem by using the multiple shooting method. A sequential quadratic programming approach is employed to derive a numerical solution. Finally simulations are conducted under a standard driving cycle and a random driving cycle with comparison to a dynamic programming based control scheme in MATLAB/Simulink platform. Simulation results verify the effectiveness of the proposed control scheme.
