1. A method comprising: creating a mission plan that dictates one or more desired parameters of a powered system as a function of at least one of distance or time during a trip of the powered system, the desired parameters including one or more settings of the powered system that control movement of the powered system during the trip, the powered system controlled during the trip such that actual parameters that are used to control movement of the powered system are based on the desired parameters of the mission plan;identifying, with a processor, at least one of the desired parameters in the mission plan that is at least one of unobtainable by the powered system or in excess of a predefined limit associated with the powered system; andcontrolling the powered system such that one or more of the actual parameters of the powered system temporarily exceed the predefined limit during the trip when the at least one of the desired parameters is at least one of unobtainable by the powered system or in excess of the predefined limit. 2. The method according to claim 1, wherein at least two of creating the mission plan, identifying the desired parameter, and controlling the powered system are performed using a closed loop control implementation without operator intervention. 3. The method according to claim 1, further comprising revising the mission plan when the powered system is controlled such that one or more of the actual parameters temporarily exceed the predefined limit or the one or more alternate parameters that are obtainable by the powered system are identified. 4. The method according to claim 3, further comprising identifying at least one of a second desired parameter in the mission plan or a function of a component of the powered system to adjust when the desired parameter in the mission plan is at least one of unobtainable by the powered system or exceeds the predefined limit, and adjusting the at least one of the second desired parameter in the mission plan or the function of the component of the powered system to accomplish the mission plan. 5. The method according to claim 3, wherein creating the mission plan includes forming the mission plan such that controlling the powered system according to the desired parameters results in at least one of decreased fuel consumption or decreased emission generation by the powered system during the trip relative to controlling the powered system according to other parameters, and wherein revising the mission plan results in a revised mission plan that includes revised desired parameters and controlling the powered system according to the revised desired parameters results in the powered system at least one of consuming more fuel or generating more emissions relative to controlling the powered system using the desired parameters of the mission plan. 6. The method according to claim 1, further comprising determining whether the predefined limit is a soft limit that can be temporarily exceeded by the powered system. 7. The method according to claim 6, further comprising determining the one or more alternate parameters for use in controlling movement of the powered system for a subset of the trip when the desired parameter has the soft limit. 8. The method according to claim 6, further comprising determining at least one of a time period or a condition to control operations of the powered system such that one or more of the actual parameters of the powered system temporarily exceed the predefined limit when the predefined limit has the soft limit. 9. The method according to claim 1, further comprising deter mining the one or more alternate parameters that are obtainable by the powered system that do not exceed a hard limit of the powered system when the one or more actual parameters exceed a hard limit of the powered system. 10. The method according to claim 1, wherein the desired parameter comprises at least one of a throttle limit, a brake rate limit, a speed, an operation time for at least one of the trip or a segment of the trip, a throttle setting, or a brake setting. 11. The method according to claim 1, wherein the powered system comprises a railway transportation system having a power generating unit that comprises at least one locomotive. 12. The method according to claim 1, wherein the powered system comprises a marine vessel having a power generating unit. 13. The method according to claim 1, wherein the powered system comprises an off-highway vehicle having a power generating unit. 14. The method according to claim 1, wherein the powered system comprises a stationary power generating station having a power generating unit. 15. The method according to claim 1, wherein the powered system comprises a network of stationary power generating stations having a power generating unit. 16. The method according to claim 1, wherein the powered system comprises at least one of a transportation vehicle or an agricultural vehicle having a power generating unit. 17. A system comprising: a processor configured to receive a mission plan for a powered vehicle to travel along during a trip, the mission plan including desired parameters of the powered vehicle that change based on at least one of location of the powered vehicle or time during the trip, the desired parameters including one or more settings used to control movement of the powered vehicle,wherein the processor is configured to determine when one or more of the desired parameters are at least one of unobtainable by the powered vehicle or in excess of a predefined limit of the powered vehicle, andwherein the processor is configured to direct the powered vehicle to be controlled according to a second alternate parameter that exceeds the predefined limit for a temporary time period. 18. The system of claim 17, wherein the desired parameters include one or more throttle settings, brake settings, or speeds used to control movement of the powered vehicle for different locations or times during the trip. 19. The system of claim 17, wherein the actual parameters include one or more actual throttle settings, actual brake settings, or actual speeds of the powered vehicle during the trip. 20. The system of claim 17, wherein the processor is configured to direct the powered vehicle to be controlled according to the second alternate parameter that exceeds the predefined limit for the temporary time period when the predefined limit is a soft limit of the powered vehicle. 21. The system of claim 17, wherein the desired parameters of the mission plan are established such that controlling the powered vehicle according to the desired parameters results in the powered vehicle at least one of consuming less fuel or generating fewer emissions during the trip relative to controlling the powered vehicle according to other parameters that differ from the desired parameters. 22. The system of claim 21, wherein the processor is configured to form a revised mission plan when the one or more desired parameters are at least one of unobtainable or in excess of the predefined limit. 23. The system of claim 22, wherein the processor is configured to form the revised mission plan having revised desired parameters of the powered vehicle such that controlling the powered vehicle according to the revised desired parameters of the revised mission plan results in the powered vehicle at least one of consuming more fuel or generating more emissions relative to controlling the powered vehicle according to the desired parameters of the mission plan.
