Abstract: The present invention relates to an applied-voltage fuzzy control process for induction motors, whose particularity is that it comprises the following steps: the measurement of a speed error (Ew) produced by the comparison between the current speed (w) of an electric motor (2) and a reference speed (wref); the generation of the derivative (dEw/dt)of this speed error; the measurement of a power error (Ep) generated by the comparison between the power supplied (Pin) to the motor (2) and a reference power (Pref); the application of a fuzzy control to the speed error (Ew), to the derivative (dEw/dt) of the speed error, and to the power error (Ep) so as to generate the values of the voltage (Vphase) and the pulse (F) that are suitable to drive the electric motor. The fuzzy control is divided into two sections: a first one (FSC) for motor speed control and a second one (FSP) for motor power control.

Abstract: A method for setting up the memory of an electronic controller operates in Fuzzy logic, whereby predetermined membership functions (f(m)) of logic variables (M), defined within a universe of discourse (U) sampled in a finite number of points (m), are subjected to inference operations basically configured by IF/THEN rules with at least one front preposition and at least one rear implication. The controller further comprises a central control unit (3) provided with a memory section (5) for storing predetermined values (l) of the membership functions (f(m)) which appear in the front or IF part of the Fuzzy rules and have a predetermined degree (G) of truth or membership. This method provides for storing into said memory section (5) the only values (l) of those membership functions (f(m)) which have a value (l) of the degree of membership (G) other than zero at the points (m) of the universe of discourse (U),.

Abstract: PURPOSE: To attain noise reduction through a filter for filtering only the noise- containing signal sections in digital video signals. CONSTITUTION: Each circuit means is operated by a fuzzy logic and provided with inference circuits (look-up tables) C1 and C2 and digital subtracters S1-S4. Each subtracter has an input terminal and is provided for receiving an individual digital video signal for reporting information concerning the pixel to be processed. The number of circuit means included in a filter 1 depends on the size of an image to be processed, and secondly, depends on the number of directions under the operation of a line operator. While using fuzzy type logic rules, a noise calculation circuit 4 compares trigger levels determined in the circuits C1 and C2 with such a trigger level. Thus, noise contained in the digital video signal are reduced effectively.

Abstract: PURPOSE: To provide high resolution of video and to eliminate the defects of conventional techniques by providing a calculation block which is connected to an input terminal and operated by a fuzzy-logic based processing method and which executes a switch between at least two different interpolation processing methods. CONSTITUTION: For a TV signal scanning converting device 1, luminance/ chrominance signals CFy and CFuv and signals PFy and PFuv corresponding to image fields are inputted to an interface(IF) 2. The IF 2 is operated with a fuzzy logic and supplies TV signals components Xy and Piy to input terminals Pi and X of a filtering block 3. A calculation block CALC1 is operated with a fuzzy logic processing method, receives a luminance component Y and detects the front and motion of a TV signal, while utilizing information in two continuous image fields. On the other hand, an arithmetic block 5 inputs an average parameter, which is calculated based on pixels (Pi , Pj and x) of image fields, to the calculation block CALC1 . A block MAX calculates and outputs the peak value of plural signals to be inputted.
