  • Patent number: 10739768
    Abstract: A system including a controller configured to, in each sampling period, minimize a distance of the autonomous vehicle from a target path by solving a constrained control problem, input sensor values and estimators that are calculated based on the sensor values and dynamic models and record the sensor values and the estimators in a memory of the controller, incorporate the sensor values and the estimators into conditions for minimizing the distance of the autonomous vehicle from the target path associated with the constrained control problem, map the conditions for minimizing the distance of the autonomous vehicle from the target path to a non-smooth system using Fischer-Burmeister function, smooth the non-smooth system and apply Newton method iterations to the smoothed system in order to converge on a solution, and issue commands including a steering command that control actuators of the autonomous vehicle based on the solution.

  • Patent number: 10578040
    Abstract: System for controlling an internal combustion engine having a variable geometry turbocharger, an EGR valve and an EGR throttle. The system includes a controller and an engine. In each sampling period, the controller inputs sensor values and estimators that are calculated based on the sensor values and dynamic models and records the sensor values and the estimators in a memory of the controller. The controller incorporates the sensor values and the estimators into conditions for optimality associated with a constrained optimal control problem, maps the conditions for optimality to a non-smooth system using Fischer-Burmeister function, performs Newton method iterations on a smoothed system approximating the non-smooth system in order to converge on a solution, and issues commands that control the EGR valve, the EGR throttle and the variable geometry turbocharger during engine operation.
