A reduced control system suitable for control of an active suspension system as a controlled plant is described. The reduced control system is configured to use a reduced sensor set for controlling the suspension 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.

1. A method for controlling a vehicle suspension system, comprising the steps of: measuring first information from said suspension system by using a first plurality of sensors; providing said first information to a first suspension control system, said first suspension control system configured to provide a desired accuracy for said suspension, said first control system providing a first control signal; measuring second information from said suspension system by using a second plurality of sensors, where said second plurality of sensors comprises fewer sensors than said first plurality of sensors; providing said second information to a second suspension control system, said second suspension control system providing a second control signal; and configuring said second suspension control system using said first suspension control signal and said second suspension control signal such that said second suspension control system will provide acceptable control accuracy when used to control said vehicle suspension system without said first suspension control system.
