English abstract:
The dynamics of a gas engine vary strongly over
its power range with controlled engine speed. The major
nonlinearities result from the turbo charger driven by exhaust
gas. The recirculation valve adjusts the power of the turbo
charger, by leading part of the compressed mixture back to the
inlet. The position of the throttle valve affects the mass flow
into the engine. Both actuators are used to control the engine
speed. In order to optimize the switching between the actuators,
LQG control is applied.
For linear state feedback control suitable states have to be
determined and unmeasured states must be estimated in an
acceptable way. This paper shows that LQG control is able to
enhance the performance of the engine speed control by using
both actuators simultaneously.
