在信息信號處理過程中,如對信號的過濾、檢測、預測等,都要使用濾波器,數(shù)字濾波器是數(shù)字信號處理(DSP,DigitalSignalProcessing)中使用最廣泛的一種器件。常用的濾波器有無限長單位脈沖響應(ⅡR)濾波器和有限長單位脈沖響應(FIR)濾波器兩種[1],其中,F(xiàn)IR濾波器能提供理想的線性相位響應,在整個頻帶上獲得常數(shù)群時延從而得到零失真輸出信號,同時它可以采用十分簡單的算法實現(xiàn),這兩個優(yōu)點使FIR濾波器成為明智的設(shè)計工程師的首選,在采用VHDL或VerilogHDL等硬件描述語言設(shè)計數(shù)字濾波器時,由于程序的編寫往往不能達到良好優(yōu)化而使濾波器性能表現(xiàn)一般。而采用調(diào)試好的IPCore需要向Altera公司購買。筆者采用了一種基于DSPBuilder的FPGA設(shè)計方法,使FIR濾波器設(shè)計較為簡單易行,并能滿足設(shè)計要求。

This paper addresses the issues relating to the enforcement of robust stability when implementing the Adaptive Inverse Control (AIC) scheme. In this scheme, an adaptive FIR filter is added to a closed-loop system in order to reduce the output error caused by external disturbances, enhancing the performance achieved by linear time-invariant controllers alone.
