    Project mention: (Direct) Collocation in (Time) Optimal Control | reddit.com/r/ControlTheory | 2022-12-09

    Howdy! Collocation methods can be... tricky. For NMPC control of vehicles, success has been had using direct multiple shooting. Also easier to implement and more intuitive. In fact, this example from the GH is pretty instructive: https://github.com/casadi/casadi/blob/master/docs/examples/python/race_car.py

  • InfluxDB
