ABSTRACT:
Control and functional isolation of an actuator applied to an internal combustion engine through an interface module which is interposed between the actuator and a controller having a control function, with state of the actuator estimated, converted to standard units of measure, and corrected in the interface module in response to an estimate of a parameter influenced by the actuator state, the parameter expressed in the standard units of measure, and the corrected state applied as feedback to the controller which, through application of the control function, issues to the module a desired state. The desired state is restored by removing a correction value from the desired state, is converted to actuator position units, and is applied to control actuator position.
