Highly Dynamic Controls for Gas Engines

Cover Story Gas Engines

When controlling gas engines, the potentials offered by installed sensors and actuators are seldom exploited to the maximum. The effects of individual control interventions interact so strongly that a compartmentalised approach requires ever more complex control structures. Using the example of a gas engine with port injection, it can be shown that clear benefits derive when the control of available actuators is interlinked.

Controller Modelling

Via the combination of several control interventions the response of a gas engine to rapid load changes is considerably improved. The control challenge lies in maintaining engine speed and emissions at predetermined values while finding an operating point that is favourable to load imposition. For this purpose gas volume, ignition timing and the position of the exhaust gas wastegate are used. Employing these actuating variables simultaneously and highly dynamically means moving from conventional simple control structures to more complex ones. A...
