Abstract
New and/or alternative approaches to performance control in an engine system having a compressor configured to receive torque from each of a turbine placed in an exhaust output of an engine and an electric motor. A control unit for the electric motor, referred to as an ETurbo controller, is provided with each of a speed control signal and a torque control signal from an engine control unit. The ETurbo controller is configured to use the torque control signal and speed control signal to operate the electric motor without causing the compressor to exceed a speed boundary.
