Create the device function for the PI controller.
- Parameters:
precision – Precision callable used to coerce scalars on device.
clamp – Callable that clamps proposed step sizes.
min_step_shrink – Most the step may shrink per adjustment.
max_step_growth – Most the step may grow per adjustment.
dt_min – Minimum permissible step size.
dt_max – Maximum permissible step size.
algorithm_order – Order of the integration algorithm.
safety – Safety factor used when scaling the step size.
error_norm – Device function returning the mean squared scaled error.
- Returns:
CUDA device function implementing the PI controller.
- Return type:
Callable
