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: PROBLEM TO BE SOLVED: To reduce image quality deterioration by correcting a pixel value according to both an global feature of a video image block to which the pixel belongs and a local feature of video areas in the vicinity of the pixel so as to attenuate grating noise and stepwise noise. SOLUTION: A global feature GF and a local feature LF of an input video image In evaluated by a feature extract block FE is fed to a fuzzy processing block FUZZY as an input, and a parameter FA proper to decision of a type of filter processing is decided according to a fuzzy criterion. A filter pattern FP decided by a filter compensation block FC is fed to a processing block PROC to which the input video image In is directly supplied and the block PROC applies filter processing of the input video image In based on the filter pattern FP. Thus, low pass filter processing is applied to video areas in the vicinity of grating noise and an edge to reduce both grating noise and stepwise noise.
