A reduced control system suitable for control of an engine as a nonlinear plant is described. The reduced control system is configured to use a reduced sensor set for controlling the plant without significant loss of control quality (accuracy) as compared to an optimal control system with an optimum sensor set. The control system calculates the information content provided by the reduced sensor set as compared to the information content provided by the optimum set. The control system also calculates the difference between the entropy production rate of the plant and the entropy production rate of the controller. A genetic optimizer is used to tune a fuzzy neural network in the reduced controller. A fitness function for the genetic optimizer provides optimum control accuracy in the reduced control system by minimizing the difference in entropy production while maximizing the sensor information content.

[ What is claimed is:] [1.]1. A method for controlling an internal combustion engine comprising the steps of: measuring first information from said engine by using a first plurality of sensors; providing said first information to a first engine control system, said first engine control system configured to provide a desired accuracy for said engine, said first control system providing a first control signal; measuring second information from said engine by using a second plurality of sensors, where said second plurality of sensors comprises fewer sensors that said first plurality of sensors, providing said second information to a second engine control systems said second engine control system providing a second control signal; and configuring said second engine control system using said first engine controls signal and said second engine control signal by generating a physical criteria and an information criteria, wherein said physical criteria is calculated by an entropy model based on thermodynamic properties of said engine.
