Abstract
A method for controlling a turbine of an engine system to achieve a desired boost pressure is provided. The method determines a desired exhaust gas pressure based on the desired boost pressure by using a model for a power balance between the turbine and a compressor of the engine system. The method generates a base command for controlling a position of a vane of the turbine based on a ratio of the desired exhaust gas pressure to a measured turbine outlet pressure.
