本論文主要探討以疊代程序做參考輸入之輸入成形控制設計並應用於雙輸入雙輸出(Double-Input-Double-Output, DIDO)系統，特別是針對雙驅動控制系統(DSA control system)以達到長行程且高精度之定位要求。本文首先對雙驅動系統模型做數學推導及模型參數討論，以此作為回授控制器設計之依據並利用獨立通道設計方法(Individual Channel Desgin, ICD)設計回授控制器以達到期望之追跡表現。然而在系統控制的過程中由於兩驅動器之互相干擾及不同的響應特性可能造成「飽和問題」(saturation problem)，本文以疊代方法對低剛性雙驅動定位系統之參考輸入做輸入成形設計，減少了系統移動過程中兩驅動器之間最大相對距離以避免飽和產生的機會且同時滿足追跡之要求，文末以模擬結果驗證本文所提出之設計方法並提供結論與未來研究方向以供參考。

This thesis outlines and demonstrates the efficacy in designing an iterative reference input shaping controller, applied to a class of Double-Input-Double-Output (DIDO) system, specifically aimed to provide long-stroke precision positioning for Dual Stage Actuator (DSA) systems. Due to the coupling effect from the interaction between the two actuators. This thesis first provides a full analysis to the characteristic of this class of DIDO system, Then secondly provide a relative distance limiting procedure that iteratively modifies the reference input provided to the DSA system. In order to individually design feedback controller for the two actuators in the DSA system, connection and mass difference for the two actuators needs to be characterized, where desired tracking performance in positioning through the individual channel feedback control design is first investigated without full consideration. Furthermore, due to the coupling (disturbance) input to the DSA actuation, this thesis researched a iterative input shaping method, in order to utilize the previously designed feedback controller, but also restrict the relative distance of the two actuators. This work demonstrates the feasibility in providing an automatic tuning algorithm, that will provide a reference input keeping the two actuators in range, focused on a low-stiffness connection.
