Locomotive control system

A locomotive control system comprising:

• a locomotive having one or more motors configured to generate torque to propel the locomotive;
• one or more sensors configured to measure a response of the locomotive to the torque that is generated by the one or more motors, the one or more sensors configured to generate sensor data representative of the response that is measured;
• and
• a hardware controller configured to direct the one or more motors of the locomotive to generate the torque according to a designated torque profile, the controller also configured to receive the sensor data and to determine a frequency spectrum of the response of the locomotive, the controller also configured to compare one or more parts of the frequency spectrum with a threshold to determine that a component of the locomotive is degraded and to automatically change movement of the locomotive responsive to determining that the component is degraded.

A locomotive control system comprising:

• an engine configured to be disposed onboard a locomotive and to receive a supply of fuel for cylinders of the engine;
• a power electronics circuit configured to be coupled with the engine and to conduct electric current to one or more motors of the locomotive for propelling the locomotive;
• one or more sensors configured to monitor direct current link voltages in the power electronics circuit coupled with the engine;
• and
• one or more processors configured to be communicatively coupled with the one or more sensors, the one or more processors also configured to change the supply of fuel to at least one of the cylinders of the engine, to determine a magnitude of a frequency in a frequency spectrum of the direct current link voltages that are monitored, and to determine whether the at least one cylinder that receives the supply of fuel that is changed is damaged or degraded based on the magnitude of the frequency that is determined.
