Abstract
A scheme for management of uncertainty in control systems that require adaptation is described. The scheme removes as much uncertainty as possible at design time and manufacturing time by taking advantage of available computer resources in pre-computing a large set of robustness-performance tradeoffs. a plant that is controlled by having model controllers and a data evaluator receive monitored signals. The monitored signals are evaluated to determine when sufficient information is received. One of the model controllers generates a control signal based upon the monitored signals received.
