Function Space Model of Multirate Digital Control Systems
多采样率数字控制系统的函数空间模型

Using function space methods and lifting techniques, this paper proposes a function space model of multirate digital control systems. This time invariant discrete time model can describe both sampling instant and inter sample behavior of the continuous plant. The controller synthesized based on this model, may eliminate ripples and oscillations between the sampling instants of the current multirate digital control systems. This model affords a new way for multirate digital control system analysis and synthesis.
