摘要
大多数使用换向控制算法的直流(DC)无刷鼓风机调速模块,会导致鼓风机电机转矩波动,使得电机输出风量稳定性下降。文章使用恩智浦MC9S12XDP100单片机设计了一种直流无刷鼓风机的调速模块,开发系统硬件和软件,设计矢量控制双闭环算法,并运用专家系统模糊比例-积分-微分(PID)在转速外环中进行参数整定。通过对转速、风量等相关参数进行测试,实验表明,本调速模块有效解决了换向控制算法带来的转矩波动问题,提高了空调鼓风机风量输出稳定性。
Most of the direct current(DC)brushless blower speed regulation module using the commutative control algorithm will lead to the torque fluctuation of the blower motor,which reduces the stability of the motor output air volume.MC9S12XDP100 is used to design the speed regulation module of DC brushless blower,and hardware and software systems are developed,and the vector control double closed-loop algorithm is designed in this paper,and the expert system fuzzy proportion integration differentiation(PID)is used to adjust the parameters in the speed outer loop.Through the test of speed,air volume and other related parameters,the experiments show that the speed regulation module solves the problem of torque fluctuation caused by the commutation control algorithm effectively and improves the output stability of air volume of air conditioning blower effectively.
