摘要
根据FIR低通数字滤波器的原理与滤波特性,通过MATLAB/Simulink软件模拟一定性能的FIR滤波器频率响应与抽头系数,用VHDL语言设计和仿真压电直线微电机控制系统中的FIR低通数字滤波器,实现用软件描述硬件的动作及其功能。
According to the principle and characteristic of FIR low-pass digital filter,through using MATLAB/Simulink software to simulate frequency response of some performance index and tap coefficients about FIR filter,design and simulate FIR low-pass digital filter in the control system of piezoelectric linear micromotor in VHDL language,It can be realized the filter’s action and function with software describing hardware.
