A control system for a power source is disclosed. The control system includes a first sensor module and a second sensor module to generate signals indicative of an ambient condition of the power source and an operating parameter of an engine of the power source, respectively. The control system further includes a controller that receives signals indicative of the ambient condition and the engine operating parameter and determines a first power output based on the ambient condition and a second power output based on the engine operating parameter. A final power output is further determined based on the first and second power outputs, which is further compared with a predetermined power output of the engine. A power conversion device that is coupled to the engine is further controlled to regulate a power output of the power source based on the comparison between the final and predetermined power outputs.
