Abstract [en]

This paper presents a novel heuristic method for_x000D_ optimal control of mixed-integer problems which for given_x000D_ feasible values of the integer variables are convex in the rest of_x000D_ the variables. The method is based on the Pontryagin€™s maximum_x000D_ principle allows the problem to be solved using convex_x000D_ optimization techniques. The advantage of this approach is the_x000D_ short computation time for obtaining a solution near the global_x000D_ optimum, which may otherwise need very long computation time_x000D_ when solved by algorithms guaranteeing global optimum, such_x000D_ as Dynamic Programming._x000D_ In this study the method is applied to the problem of battery_x000D_ dimensioning power split control of a plug-in hybrid electric_x000D_ vehicle where the only integer variable is the engine on/off_x000D_ control, but the method can be extended to problems with more_x000D_ integer variables. The studied vehicle is a city bus which is_x000D_ driven along a perfectly known bus line with a fixed charging_x000D_ infrastructure. The bus can charge either at standstill, or while_x000D_ driving along a tram line (slide-in)._x000D_ The problem is approached in two different scenarios: first,_x000D_ only the optimal power split control is obtained for several fixed_x000D_ battery sizes, second, both battery size power split control_x000D_ are optimized simultaneously. Optimizations are performed over_x000D_ four different bus lines two different battery types, giving_x000D_ solutions that are very close to the global optimum obtained by_x000D_ Dynamic Programming._x000D_
