摘　　要：随着社会经济上行,人们生活压力增大,每个人对于睡眠质量的要求与日俱增,更多患有睡眠呼吸障碍的患者开始尝试利用家用睡眠呼吸机辅助睡眠,以此减少睡眠过程中呼吸暂停、呼吸道塌陷等状况的发生。国产家用睡眠呼吸机起步较晚,当下,研究一款全国产化、高效无感无刷直流电机的控制平台是抢占国内睡眠呼吸机市场的重中之重。为了适应呼吸机对转速精准控制的超高要求,在国产单片机HC32F460JETA中采用FOC矢量控制作为整个算法核心,FOC算法运行时间占70%以上;并采用三电阻电流采样方式对电机运行过程中相电流采样,采样电压经过滑膜观测器确定转子的位置,分段PID控制提高转速的快速响应。并通过实验论证国产化FOC矢量控制无感无刷直流电机控制系统的可行性。With the upward social economy,people’s living pressure increases,and everyone’s requirements for sleep quality are increasing,more patients with OSAS begin to use home sleep ventilator to help sleepy well,in order to reduce the occurrence of apnea,respiratory collapse and other conditions during sleepy.Domestic home sleep ventilator started late,at present,the study of a domestic,efficient non-inductive BLDCM control platform is the top priority to seize the domestic sleep ventilator market.In order to adapt to the high requirements of precision speed control of the ventilator,FOC vector control was used as the core of the whole algorithm in the domestic MCU HC32F460JETA,and the running time of FOC algorithm accounts for more than 70%.The three-phase current sampling method was used to sample the phase current during the operation of the motor.The sampling voltage was determined by the synovial observer,and the piecewise PID control could improve the fast response of the speed.The feasibility of domestic FOC vector control brushless DC motor control system was demonstrated by experiments.
