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.
