Claim One:
1. A control system ( 100 ), comprising: an actuator ( 124 ) for positioning a control device ( 130 ), the control device defining a flow path through an aperture, the aperture defining a pressure drop along the flow path, and comprising a control surface, wherein the actuator ( 124 ) positions the control surface in order to regulate fluid flow across the pressure drop based on a model state; a control law ( 111 ) for directing the actuator ( 124 ) as a function of a model output; and a model processor ( 110 ) for generating the model output, the model processor comprising: an input object ( 220 ) for processing model input and setting a model operating mode; a set state module ( 420 ) for setting dynamic states of the model processor ( 110 ), the dynamic states input to an open loop model ( 410 ) based on the model operating mode; wherein the open loop model ( 410 ) generates a current state model as a function of the dynamic states and the model input, wherein a constraint on the current state model is based on a series of cycle synthesis modules, each member of the series of cycle synthesis modules modeling a component of a cycle of the control device ( 130 ) and comprising a series of utilities, the utilities based on mathematical abstractions of physical properties associated with the component, the series of cycle synthesis modules including a flow module for mapping a flow curve relating a compressible flow function to a pressure ratio and for defining a solution point located on the flow curve and a base point located off the flow curve; an estimate state module ( 440 ) for determining an estimated state of the model based on a prior state model output and the current state model of the open loop model; and an output object ( 240 ) for processing the estimated state of the model to determine the model output.
