模糊控制器优化方法及其在传感器补偿中的应用
摘要
为了减小压力传感器温度漂移造成的测量误差
使用0阶T—S模糊控制器对压力传感器温度附加误差进行校正
校正后的误差为±0.3%
且零位温度系数和灵敏度温度系数都降低1个数量级以上。使用模拟退火算法对模糊规则进行寻优
提高了校正精度
并保持了0阶T—S模糊控制器运算简单和速度快的特点
使之能快速地完成传感器的温度补偿。
Abstract
An error collection method for a kind of pressure sensor based on zero-order T-S fuzzy logic controller is presented.Simulated annealing algorithm is used to optimize the parameters of the fuzzy rules.After the temperature compensation
the error is corrected within ±0.3 %
and the temperature coefficients are reduced greatly.Compared to other compensation techniques
it is a new
efficient compensation method that not only increases the compensation precision but also maintains the fast calculation ability of the zero-orde T-S fuzzy logic controller.
