Abstract: Methods and systems are provided for monitoring a fuel injector of an internal combustion engine. In one embodiment, a method includes: receiving a set of feature data, the feature data sensed from a fuel injector during a fuel injection event; processing, by a processor, the set of feature data with a decision tree model to generate a prediction of a fault status; and selectively generating, by the processor, a notification signal based on the prediction.

Abstract: A method for using a closed-loop control system to control an autonomous system is disclosed, the closed-loop control system comprising an explicit Nonlinear Model Predictive Control (NMPC) framework. The method (i) computes operation parameters for the autonomous system using the closed-loop control system, the output of the explicit NMPC framework comprising the operation parameters; (ii) modifies the output of the explicit NMPC framework to consider unmeasured system states, unknown system model values, and external disturbances, to create modified operation parameters, using an extended high-gain observer (EHGO) to estimate the unmeasured system states and the external disturbances and a dynamic inverter to compute values of unknown input coefficients for a system model of the autonomous system; (iii) generates a modified output signal including the modified operation parameters; and (iv) transmits the modified output signal to control operation of the autonomous system using the modified operation parameters.
