Abstract

A method of operating an engine assembly is provided. The engine assembly comprises an engine and a turbocharger assembly, wherein a control parameter of the turbocharger assembly is controllable in order to control a level of boost provided by the turbocharger assembly. The method comprises determining a desirable pressure limit of exhaust gases upstream of a turbine of the turbocharger assembly, predicting a desirable limit value of the control parameter to be applied to the turbocharger assembly in order to achieve the desirable pressure limit, determining an error in the desirable limit value of the control parameter, adjusting the desirable limit value of the control parameter based on the error, and controlling the operation of the turbocharger assembly such that the adjusted limit value is not exceeded.
