Abstract: A method for monitoring a reliability of an output of a sensor fusion system of a vehicle is disclosed. At first, an input data, including sensor data obtained over a period of time from each of vehicle-mounted sensors, which are configured to monitor a surrounding environment of the vehicle, of the sensor fusion system is stored. Perception output data that is output from the sensor fusion system, includes object detections and free-space area indications in the surrounding environment of the vehicle. The obtained perception output data is then compared with the stored input data and determined whether any object detections indicated in the obtained perception output data is indicated in the field-of-view of that sensor in order to validate any object detections and free-space area indications in the obtained perception output data. Accordingly, a signal indicative of a status of the sensor fusion system is outputted.

Abstract: A doubly fed induction generator (DFIG) speed control system is provided. The system includes a wind turbine and a wound rotor induction generator connected to the wind turbine through a drive train system and to a power grid.

Further, the method includes determining a back-up stop trajectory within the finite time horizon. The back-up stop trajectory has a starting state and terminating in a final state, where the final state is defined as a safe state. The method further includes forming a terminal set of states within the finite time horizon based on at least one predefined constraint, wherein the terminal set of states includes a terminal state that corresponds to the starting state for the back-up stop trajectory. Moreover, the method includes generating a nominal trajectory for at least a portion of the finite time horizon based on a constraint controlled technique.
