COMPRESSOR OUTLET PRESSURE CONTROL FOR IMPROVED ENGINE SPEED STABILITY AND PERFORMANCE USING COMPRESSOR RECIRCULATION VALVE AND TURBOCHARGER WASTEGATE

Systems, methods and apparatus are disclosed for producing a target compressor outlet pressure that is based on a desired pressure differential across an intake throttle of an internal combustion engine and an intake manifold pressure by opening or closing a compressor recirculation valve and a turbocharger wastegate to commanded positions based on the target compressor outlet pressure.
