Abstract
A method of controlling an engine exhaust temperature and an exhaust mass flow rate for stationary regeneration of an engine exhaust gas particulate filter of an engine. The method implements a feed forward control that sets an EGR valve position and an injection timing associated with the engine, and a sets an engine speed. The method implements a feed back control that sets a turbo waste gate position and an intake throttle position associated with the engine.
