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 - TSADAPTBASICbut 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.
