摘　　要：为了满足电机实时控制的要求和转矩控制精确的要求,数字滤波的相频特性需具有不依赖运行频率的特质。依据有限脉冲响应(FIR)滤波器原理研究设计了一种数字化线性滤波器。利用Simulink仿真平台确定线性滤波器合理的阶数、结构参数和相位偏移补偿算法。试验验证了FIR低通滤波器在电机控制上的适用性。In order to meet the demand of real-time control and precise torque control for electric motor, the phase frequency features of linear filter need to have the trait of not rely on operating frequency. A digital linear filter using FIR filter principle was designed. Using Simulink platform to validate filter functions, so as to determine reasonable order number, structure parameters and the phase offset compensation algorithm of filter. The applicability of linear filter on motor control engineering has been proved by experiments.
