Abstract
An apparatus, system, and method are disclosed for predictive control of a turbocharger. The method includes interpreting a compressor performance model for a turbocharger, and interpreting at least one current operating parameter. The method further includes calculating a performance margin, calculating a performance margin derivative, and calculating a response value. The performance margin comprises a choke margin or a surge margin according to the position of an operating point in the compressor performance model. The performance margin is implemented in a first sigmoid function, and the performance margin derivative is implemented in a second sigmoid function. The response value is determined by applying a MIN function to the output of the product of the sigmoid functions in the choke margin case, and by applying a MAX function to the product of the sigmoid functions in the surge margin case.
