【Abstract】 A method for temperature compensation of fiber Bragg grating current sensor based on artificial neural network is presented in this paper. The output characteristics of FBG current sensors are analyzed. It is found that the response of the current sensor is nonlinear and the sensor suffers from the influence of temperature, which is hard to avoid. The paper introduces the way to solve the above problems by creating a neural network, training the network and simulating the network with Matlab language. It is revealed from the simulation results that the influence of environmental temperature fluctuation can be eliminated effectively.更多还原
