摘要:
为了提高MEMS陀螺仪的温度性能,基于东南大学自主设计的TC10号温控陀螺表头,设计了一种芯片级温控系统.首先,研究了微加热丝和微热敏电阻的材料、结构以及表头的加工工艺,分析了温控系统的工作原理.然后,建立了表头内部的温度模型,利用Ziegler-Nichols经验参数法,确定了PID参数并进行系统仿真,验证了控制系统的快速性和稳定性.最后,结合模型和仿真参数设计了温控电路,并通过温度实验得到了微热敏电阻的温度特性曲线.结果显示:温控系统可将表头内温度控制在设定温度点附近;表头腔内温度和驱动模态谐振频率在-20~60 ℃范围内的变化量分别由温控前的78.453 ℃和3.76 Hz下降到温控后的4.949 ℃和0.48 Hz,由此验证了芯片级温控技术的可行性.
Abstract:
To improve the temperature characteristic of a micro electro mechanical system(MEMS)gyroscope, an on-chip temperature-controlling system is designed based on the gyroscope structure chip TC10 designed by Southeast University. First, the material and structure of a micro heater and a micro thermal resistance are discussed and the working principle of the temperature-controlling system is analyzed. Then, the temperature model of the gyroscope chip is established. The proportion integration differentiation(PID)parameters are determined by using the Ziegler-Nichols method. The system model is simulated, and the rapidity and stability of the system is proved. Finally, the controlling circuit is designed through combining the model and the PID parameters. The temperature curve of the micro thermal resistance is drawn through the temperature experiments. The results show that the temperature in gyroscope chip can be controlled near the controlling point in thermal experiments. With the temperature controlling, when the ambient temperature ranges from -20 to 60 ℃, the temperature variation in gyroscope chip decreases from 78.453 to 4.949 ℃, and the variation of drive mode resonance frequency changes from 3.76 to 0.48 Hz, which proves the feasibility of the on-chip temperature-controlling technology.
