Condition control is defined as the interactive processes of condition monitoring, condition analysis, and condition response. A model is presented which employs the use of expert systems to achieve real-time condition control of a hydraulic system. The approach focuses on the use of fuzzy logic to achieve machine intelligence to monitor and analyze pre-degradation ‘incipient’ failure and impending conditions. Also discussed are the corresponding real-time ‘reactive’ condition responses, coupling system control with condition control.
