TSAdaptDSPSetFilter#

Sets internal parameters corresponding to the named filter [SoderlindW06] [Soderlind03]

Synopsis#

#include "petscts.h" 
PetscErrorCode TSAdaptDSPSetFilter(TSAdapt adapt, const char *name)

Collective

Input Parameters#

  • adapt - adaptive controller context

  • name - filter name

Options Database Key#

  • -ts_adapt_dsp_filter - Sets predefined controller by name; use -help for a list of available controllers

Filter names:

  • basic - similar to TSADAPTBASIC but with different criteria for step rejections.

  • PI30, PI42, PI33, PI34 - PI controllers.

  • PC11, PC47, PC36 - predictive controllers.

  • H0211, H211b, H211PI - digital filters with orders dynamics=2, adaptivity=1, filter=1.

  • H0312, H312b, H312PID - digital filters with orders dynamics=3, adaptivity=1, filter=2.

  • H0321, H321 - digital filters with orders dynamics=3, adaptivity=2, filter=1.
