# TSAdaptDSPSetFilter
Sets internal parameters corresponding to the named filter 
## Synopsis
```
#include "petscts.h" 
PetscErrorCode TSAdaptDSPSetFilter(TSAdapt adapt, const char *name)
```
Collective on adapt


## Input Parameters

- ***adapt -*** adaptive controller context
- ***name -*** filter name



## Options Database Key

- ***-ts_adapt_dsp_filter <name> -*** 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.
