Abstract
The invention relates to a method for stabilizing a controller and to the use of that method for stabilizing a controller system in an internal combustion engine. It is proposed that the stability of the controller first be established or excluded, that the control characteristic of the controller be altered and that the stability be checked again, and that those steps be repeated in a loop. For use in internal combustion engines, it is proposed that the order of precedence for the stabilization be specified and optionally made dependent on external ambient parameters.
Claims11
A method for stabilizing a controller using a control loop, the method comprising:
- detecting an instability of the controller;
- altering a characteristic of the controller;
- and
- detecting an alteration of the control behavior of the controller.
A controller device, comprising:
- a controller arrangement;
- a detecting unit;
- an altering unit;
- and
- a stabilizing arrangement to stabilize the controller arrangement by using a control loop and by using the detecting unit to detect an instability of the controller arrangement, using the altering unit to alter a characteristic of the controller arrangement, and by detecting an alteration of the control behavior of the controller arrangement.
