摘要

阐述了FIR和IIR两种滤波器各自的优点和缺点，针对它们的不足之处，结合正交基函数理论，在FIR滤波器的基础上进行了改进。改进后的滤波器兼有FIR和IIR两种滤波器的优点。接着，依据改进后的滤波器，给出了对应的前馈控制算法。最后，对算法进行了仿真分析和实验验证，结果表明，该算法具有很快的收敛特性和良好的稳定性，可以推广至工程应用。

Abstract

The advantages and disadvantages of Finite Impulse Response (FIR) filter and Infinite Impulse Response (IIR) filters were discussed in this paper, aiming at the disadvantages, some improvements on FIR filter were made using orthonormal basis functions. The improved filter has both advantages of FIR and IIR filters. Then, the feedforward control algorithm based on the improved filter was designed. Finally, simulation analysis and vertical tail experimental verification for the new algorithm were given. The results demonstrated that the feedforward control algorithm in this paper has good performances such as fast convergence and robustness, so it is feasible to practical engineering application.
