摘要： Variation in results of a semiconductor fabrication process is minimized by adjusting process parameters utilizing a fuzzy-controlled learning feedback system. The fuzzy-controlled learning system receives as inputs the results of the fabrication process and then converts these results into a fuzzy set defined by a membership function. An inference engine applies a fuzzy rule base to map an output fuzzy set from the input fuzzy set. The fuzzy output set is then converted to crisp outputs which automatically adjusts parameters of the fabrication process in order to minimize variation.

摘要： To maximize the production run speed of a sheet fabrication machine such as a turret punch press, and yet at the same time maintaining the requisite accuracy for each part produced from the production run, historical data pertaining to the various parameters for effecting the positioning moves of a worksheet are measured and collected using a reference machine or a prototype machine. For each positioning move to be effected, the CNC controller of the system retrieves the historical data from a database and, using that historical data, calculates the various parameters that affect the positioning move. By using fuzzy logic, the controller becomes, in a sense, self teaching, especially if updated historical data are provided to its database store to enhance the accuracy for later positioning moves. In addition to measuring and collecting historical data from reference or prototype machines, static process control (SPC) tests may be performed for different types of worksheets under different loads. The data collected from the SPC tests are stored and can be used as the historical data. Using historical data to calculate the next positioning move, i.e., by using the past to forecast or predict the future, the maximum allowable speed is obtained for each positioning move. At the same time moves that will produce parts that have dimensions that are within the predetermined required accuracy threshold are ensured.

摘要： A computing entity obtains product information corresponding to a product and defines a multi-region metric space vector based on the product information. The multi-region metric space vector is a vector within a multi-region metric space that comprises a first region corresponding to supply chain/component information, a second region corresponding to assembly/fabrication information, and a third region corresponding to usage/usage environment information. Each of the first, second, and third regions are multi-dimensional. The computing entity processes the multi-region metric space vector using a component, assembly, and usage perspicacity model configured to define fuzzy clusters within the multi-region metric space; determines a parameter corresponding to the product based on at least one fuzzy cluster to which the perspicacity model assigned the multi-region space vector; and provides or causes providing of (a) a visual/audible representation of the parameter or (b) a machine-readable representation of the parameter as input to an application/program.

摘要： A feedback compensating apparatus for adjusting the working condition of a working machine of a working system adapted to process working portions of successive workpieces under control of a machine controller, which determines the working condition from an extraneous signal. The apparatus is used with the controller and a measuring device for measuring the dimensions of the processed working portions of the workpieces, and includes a device for obtaining dimensional data based on outputs of the measuring device during and/or after a working operation of the machine on each workpiece. The dimensional data include a dimensional error of the processed working portions, and a variable indicative of a tendency of change in the dimensional error. The apparatus further includes a device for determining the extraneous signal based on the dimensional data, and applying the signal to the machine controller to adjust the working condition of the machine. Also disclosed is a method of processing workpieces using the apparatus.

摘要： A method of controlling the movements of a multi-actuator electromechanical system having a matrix of locally interconnected analog cells associated therewith is provided. Each cell represents a hardware implementation of a model of fuzzy inference rules. The model includes a fuzzy circuit architecture which may be implemented in an integrated circuit with VLSI CMOS technology that generates and controls a reaction diffusion mechanism typical of auto-waves using a fuzzy neural network. The fuzzy neural network defines the functional relationships that may duplicate simultaneous reaction diffusion equations. The duplication of the simultaneous reaction diffusion equations is provided using two sets of fuzzy rules processing, in a linguistic manner, the state variables of the cells. An oscillatory type dynamic is imposed on each cell where two dynamic processes having different kinetic characteristics coexist.

摘要： A fuzzy controller controls a track seeking operation and a track following operation for an actuator in accordance with a position error between a present position value and a reference value. When the actuator is in track seeking operation, the actuator is accelerated or decelerated based on a velocity error value between an actual velocity value of the actuator and a target velocity value determined from a velocity profile according to the position error. In a deceleration control of the actuator, a fuzzy inference value generated based on the velocity error value and its differentiated velocity error value is used for a control of the actuator, thereby reducing an occurrence of overshooting at a target track.

摘要： An apparatus for feedback adjusting the working condition of a working machine on the basis of measured dimensions of processed workpieces, including a determining device for determining automatic and manual compensating values, and an applying device for applying the automatic and manual compensating values (Ui, U') to a machine controller for adjusting the machine working condition. The determining device determines the automatic compensating value on the basis of first or second estimated dimensional values of the workpieces obtained in an automatic compensating cycle. Each first estimated dimensional value is a sum of an actually measured dimension (X) of the workpiece and a last compensating value (U'), while each second estimated dimensional value is a sum of the actually measured dimension, the last compensating value and a previous compensating value (Ui-2, Ui-1) preceding the last compensating value. Also disclosed is a method of feedback adjusting the machine working condition.
