摘要： A method of processing readings in a measurement instrument is provided to allow for faster updates when dealing with very complex characterization equations. The present method calculates the exact and precise process variable utilizing these complex equations somewhat infrequently, while providing the ability to perform updates using a less complicated characterization equation estimation according to Taylor's theorem. By accomplishing faster update rates, the mesurement instrument provides a process control system with the necessary speed and performance to accomplish tighter control.

摘要： A power plant water chemistry analysis apparatus and method relies upon water chemistry sensors to obtain power plant water chemistry data (34) characterizing the chemical activity of a power plant water system. An analytical model processor (36) is used to generate model predictions for the power plant water system. A statistical data fitting processor (38) selects screened data from the power plant water chemistry data that corresponds to the model predictions. The screened data is processed by an artificial intelligence processor (40) to derive power plant water chemistry diagnostic information (42). The artificial intelligence processor (40) includes an expert system (50), rule base (52), plant water chemistry system simulator (54), and pattern recognition module (56).

摘要： A method and system for monitoring an industrial process and a sensor. The method and system include generating a first and second signal characteristic of an industrial process variable. One of the signals can be an artificial signal generated by an auto regressive moving average technique. After obtaining two signals associated with one physical variable, a difference function is obtained by determining the arithmetic difference between the two pairs of signals over time. A frequency domain transformation is made of the difference function to obtain Fourier modes describing a composite function. A residual function is obtained by subtracting the composite function from the difference function and the residual function (free of nonwhite noise) is analysed by a statistical probability ratio test.

摘要： The invention relates to a method for diagnosing and detecting the cause of a defect in a technical installation (1). A reliable, flexible and simple option for diagnosing said installation is provided by an array of state variables (M) characterising an operational state of the technical installation (1) in a dependent tree (A) and by determining an error path (F) in dependent tree (A), whereby changes in directions (V) of diagnosis parameters (D) contained in the dependent tree (A) are combined.

摘要： An expert system is used to perform surveillance, diagnosis and prognosis of a plant such as a nuclear reactor used in electrical power generation. The expert system uses one of real time actual plant data, previously stored actual plant data or simulated plant data as plant condition data to perform an evaluation of operating conditions in the plant. When real time actual plant data is used, a data acquisition system supplies the plant condition data. The expert system accesses the plant condition data, regardless of its source, periodically as a surveillance frame is triggered by the rules in the root frame controlling the expert system. Other frames in the expert system perform diagnosis and prognosis of the plant condition.

摘要： A controller implemented in a heating, ventilation and air-conditioning (HVAC) distribution system provides improved control by implementing a general regression neural network to generate a control signal based on identified characteristics of components utilized within the HVAC system. The general regression neural network utilizes past characteristics and desired (calculated) characteristics to generate an output control signal. The general regression neural network is implemented in a feedforward process, which is combined with a feedback process to generate an improved control signal to control components within the HVAC distribution system. Implementation of the general regression neural network is simple and accurate, requires no input from an operator supervising the controller, and provides adaptive, real-time control of components within the HVAC distribution system.

摘要： A chemical monitor system is disclosed that controls a multiplexable valve array (90) to route a fluid sample from any of plural fluid sample sources (20-38) to any of plural monitors (142-160) which will produce the most valuable chemistry measurement for diagnosing any existing or suspected malfunction. Fluid regulators (170-188) keep the flow rate constant regardless of the number of monitors (142-160) connected to a particular source. A computer (200) configures the array (90) based on the usefulness of sample analysis to a diagnostic system.
