Modeling and Simulation of Hall Voltage Sensor Based on Physical Modeling Environment

Abstract

Abstract.Hall voltage sensor is one of the most widely used sensors in the field of today's electronic measurement. It can completely replace the traditional transformer and shunt, and with the advantages of high precision, good linearity, wide frequency band, fast response, strong overload capacity and without losing the energy of measurement circuit, etc. This article by MATLAB / simulink simulation tool establishes under a Simscape modeling environment can reflect the hall voltage sensor measurement principle, internal mechanism and the measurement error of the simulation model. The model reflects the principle and internal structure of the closed-loop hall voltage sensor, introduces the interference terms such as noise, and the model has no load effect on the measuring circuit, so that the simulation system can better reflect the actual situation.
