The method of design of analog measurement systems based on fuzzy logic Multisensor

摘要

The method of design of analog multisensor measurement systems based on fuzzy logic, the present invention provides a method to design analog measurement systems that make use of MultisensorSensors and detectors or binaries, such as magnetic sensors, thermal, capacitive, inductive, and the intensity of light.Typically, detection systems are capable of measuring a given magnitude and specific values of outputs to a set of inputs.Based on fuzzy logic, the method of the project carries out the interpolation between the output signals of the detector elements of the system multisensor in order to ascertain.With high precision and linearity, wide measuring range, designed.The present invention is not yet implemented fuzzy logic in an innovative way and compact in a completely analog hardware, ensuring, when compared to software implementations.Low cost, simplicity and good frequency response.For this, the method relies on a new approach about the typical fuzzificau00e7u00e3o interface, using the static curve of each sensor detector as the function of the relevance of the fuzzy system.An electronic circuit, in turn, implements the procedure of fuzzy inference and defuzzificau00e7u00e3o, based on the method of Takagi - Sugeno.In this way, the method ensures shorter response time and higher resolution of the measurement system.
