摘要： Fuzzy logic rules are applied to a method for indirectly measuring a physical signal to be monitored which would be difficult to directly measure. The measuring method comprises the steps of obtaining a derived physical signal from the physical signal to be monitored and measuring a value of the derived physical signal and its variations over time at suitably selected check points. A first set of fuzzy logic rules are applied to ascertain the presence or absence of an index signal adapted to mark at least first, second and third operational zones of the derived physical signal. Only the second operational zone is characterized by the presence of the index signal. First and second significant values of the physical signal to be monitored are measured as start and end values, respectively, of the second operational zone. An apparatus for indirectly measuring a physical signal is also disclosed.

摘要： In a fully digital PWM controller employing a sine-triangle modulating technique, the method includes the step of linearizing the dependence of the selected scanning frequency of the memory containing the digital samples of the modulating sinusoid, from the value of the digital selection datum, and improves regulation at low speed by improving the resolution of selectable frequency values. The PWM driving signals produced by a fully digital controller implementing the linearization step of the invention show an F.F.T. extremely close to the F.F.T. of comparable PWM driving signals produced through a conventional analog technique.

摘要： A control device for a focusing system of a compact disk (CD) reader is provided. The control device uses fuzzy logic incorporated to the audio data processing system of the CD reader which is adapted to detect and segregate a light beam reflected by the surface of the compact disk from an incident light beam to the surface. The fuzzy logic control device receives a focus error signal and a derivative of the focus error. It then calculates, using appropriate membership functions, output signals to provide to a focusing servo-system of the CD reader to adjust the distance of the focal plane from the light beam detecting circuitry.
