The frequency response of sampled - data control systems is studied in detail. the presently accepted definition of the frequency response and the relatedcomputation with time - domain and frequency - domain lifting techniques are analyzedand discussed, and it is pointed out that the frequency response thus obtained isindeed the frequency response of the lifted system. because the frequency responseof the system can not be preserved by lifting, the frequency response of the liftedsystem has nothing to do with the real frequency response of the sampled - datacontrol system

Hence analysis and design of nonlinear sampled - data systems has been, in recent years, a subject of growing interest in the international community of control research. when a continuous - time plant is controlled using a digitally implemented controller, it is often faced that a continuous - time plant is transformed into its equivalent discrete - time model. a digital controller is usually designed on the base of approximate discrete - time models of the continuous - time nonlinear systems because it is difficult to obtain the closed form of the exact discrete - time model for nonlinear control systems
利用計算機等一類離散控制裝置來控制連續時間的受控對象時，都會遇到把連續時間系統化為等價的離散時間系統的問題，通過采樣器和保持器來實現離散時間的采樣控制，對于非線性連續受控系統，由於連續系統的時間離散化后一般得不到其等價的精確離散化模型表示的有限形式，實際上由其近似離散化模型代替來設計控制器，而近似會引起信號失真，那麼基於近似離散化模型上設計的采樣控制器，它是否同樣對原連續受控系統有效 -
