摘　　要：为提高传感器的动态测量精度,提出了一种基于改进烟花算法的动态补偿器设计方法。依据传感器输入输出的动态标定数据,运用改进后的烟花算法逆向建模获取动态补偿滤波器,以改善原传感器系统的动态性能。经仿真实验测试,验证了该方法的可行性。将方法应用于科氏质量流量计变送器的动态补偿测试,实验结果表明,基于改进烟花算法的动态补偿方法可以有效提高科氏质量流量计变送器的动态特性,动态响应时间减小了将近90%。In order to improve the dynamic measurement precision of sensor,a design method of dynamic compensator based on improved fireworks algorithm is presented.The optimal dynamic compensation system for the sensor is obtained by using the calibration data of the sensor and combining with the improved fireworks algorithm.The feasibility of the proposed method is verified by simulation experiments.And the experimental results show that the dynamic compensation method based on the improved fireworks algorithm can effectively improve the dynamic characteristics of Coriolis mass flowmeter transmitter,and the dynamic response time was reduced by about 90%.
