Abstract: A method for operating an internal combustion engine includes monitoring engine parameters using an electronic controller, determining a surge speed limit for the engine based on a compressor map, determining an offset engine speed based on a margin between the surge speed limit and an engine speed, determining a minimum engine speed based on the margin, applying the offset engine speed to an engine speed signal to provide an adjusted engine speed, and applying the adjusted engine speed to a desired engine speed when a speed of the engine approaches the surge speed limit.

Abstract translation: 用于操作内燃机的方法包括使用电子控制器监测发动机参数，基于压缩机映射确定发动机的喘振速度限制，基于浪涌转速极限和发动机转速之间的余量来确定偏移发动机转速， 基于所述余量确定最小发动机速度，将所述偏移引擎速度应用于发动机速度信号以提供调整的发动机速度，以及当所述发动机的速度接近所述喘振速度极限时将调整后的发动机转速应用到期望的发动机转速。
