    A new type of model-reference adaptive control system is presented. The system state estimator of this adaptive system is described by the differential equation of the reference model with the feedback speeding up the estimator action during the tuning-up of the controller parameters and vanishing when the system performance approaches that of the reference model. This model-reference adaptive con... View full abstract»

    It has been established that, by directly representing a system's components and their interactions, causal models lead to algorithmic methods for the monitoring, diagnosis, and control of fault recovery. Analysis of sensor data with component-oriented models has demonstrated that: (1) sensor failure is easily identified, (2) the absence or degradation of sensor data is easily accommodated once re...

    The idea of a two-level control scheme, the A/E (adaptive/expert) controller, is introduced as a way to optimize the behavior of an adaptive controller using expert system techniques. The proposed structure uses a constant expert system sampling interval and 14 features to describe the state of the adaptive controller. Key issues discussed are the transformation of signal domain data for use by th... View full abstract»

    A knowledge-independent planning approach for a class of structured problems is discussed. The planning method is based on abstraction of the search space. It is shown that if the search space has the substitution property (substitution partitions), then a hierarchy of abstract spaces can be realized in which each space is a homomorphic image of its predecessor. The determination of the substituti... View full abstract»
