摘　　要：为了向老年人提供居家自动化测量血糖的智能装备,设计了基于模糊比例积分微分(PID)的家用血糖智能感知装置刺针自适应控制方法.首先给出了家用血糖智能感知装置的总体设计,然后为确保刺针运动过程的稳定性,建立了刺针控制模块的动力学模型,并提出了基于模糊PID的刺针自适应控制方法,以实现刺针控制模块工作过程中PID控制器参数的自适应在线整定,采用基于模糊PID的刺针自适应控制方法的系统调节时间仿真结果为0.30 s.最后,试制并测试了家用血糖智能感知装置,原型装置调节时间测试结果为0.35 s,能抑制刺针抖动.In order to develop a kind of automatically household smart blood glucose meter for the elderly,the finger-prick adaptive control method was investigated based on fuzzy PID(proportional integral derivative) for household smart blood glucose meter.Firstly,the overall structure of household smart blood glucose meter was put forward.Then, the dynamic analysis model of fingerprick control module was established to guarantee the stability of the finger-prick movement process,and then the finger-prick adaptive control method based on fuzzy PID was proposed,which was used to implement the adaptive online tuning of the PID controller parameters during the finger-prick process. The simulation results show that the adjustment time of the system with the finger-prick adaptive control method based on fuzzy PID is 0.30 s. Finally,performances of the household smart blood glucose meter prototype were measured. The testing results show that the adjustment time of the prototype is 0.35 s,and can effectively prevent finger-prick flutter.
