基于混合优化算法的压力传感器温度补偿
Temperature Compensation of Pressure Sensor Based on Hybrid Optimization Algorithm*
摘要
Abstract
Aiming at the temperature drift of the pressure resistance sensor,the measurement accuracy is greatly af?fected by the temperature,and the temperature compensation model of pressure sensor is established by using the least square fitting method and the RBF neural network. The RBF neural network is used to compensate the low tem?perature and high temperature region,and the least square fitting method is used to compensate the middle linear re?gion. At the same time in order to improve the RBF neural network fitting effect,using the evolutionary algorithm and the descent gradient algorithm to optimize the RBF neural network parameters. Experimental results show that the use method and simple use of RBF neural network and least square fitting method for temperature compensa?tion,has higher training efficiency and effect of temperature compensation,can improve the pressure sensor under various environmental measurement precision and reliability.关键词
