摘要 针对非晶材料巨磁阻抗效应,设计并实现了一种新型磁场测量传感器,根据非晶丝的双峰特性,分析传感器的工作原理,设计传感器的闭环负反馈结构,建立了传感器的数学模型.在此基础上,通过分析传感器的误差传递函数,提出一种比例积分控制规律,可有效地消除传感器的稳态误差,提高传感器的线性度.实验结果表明:在该控制器的作用下,传感器的线性度优于0.2%,灵敏度达到1.759V/Oe,所设计的传感器具有较好的性能指标. Based on the giant magneto-impedance principle of amorphous materials,a novel magnetic sensor is presented and developed.According to double peaks feature of the amorphous,the working principle is ana-lyzed.The sensor structure with closed loop negative feedback is designed,and the mathematical model of the sensor is deduced.By analyzing the error transfer function of the sensor,PI controller is proposed,which can e-liminate the steady state error and improve the linearity.The experimental results show that the performance of the sensor is improved by PI controller.The linearity is within 0.2%and the sensitivity is up to 1.759 V/Oe.
