operation and maintenance schedule of a steam turbine plant operations. a fossil fuelled power plant is an example of bulk energy converter from fuel to electricity using 'water' normally unheated, to headers and water drum. its accessories include a safety valve, a water-level indicator and level controller. the feed-water of the
thickeners are designed to separate clear and reusable water from concentrate underflow. conventional feedback control has not been effective in stabilizing the process operation when the characteristics of the feed changes over time, since process dynamics exhibits high non-linearity. this work presents an expert system for an industrial
