具有误差补偿结构的负反馈系统及其应用
Abstract:
本发明提供一种具有误差补偿结构的负反馈系统，此系统包含：第一代数和模块，其接收一个系统输入且输出一个第一代数和模块的运算；一个第一向前模块，其耦接该第一代数和模块以接收该第一代数和输出，且输出一个第一向前模块的运算；反馈模块，其耦接该第一代数和模块和接收第一向前模块的输出且输出一个反馈模块的运算给该第一代数和模块，其中该第一代数和输出等于该系统输入减该反馈输出；误差补偿模块，其有一个补偿增益并耦接到该第一代数和模块以接收该第一代数和输出且输出误差补偿模块的运算，其中该补偿增益被调整来提供一个预定值给误差补偿输出，以便该系统输出的输出误差通过结合该误差补偿输出而被除去。
Abstract(English):

A negative feedback system includes a first summation module for receiving a system input and outputting a first summation output. A first forward module is coupled to the first summation module for receiving the first summation output and outputting a first forward output. A feedback module is coupled to the first summation module for receiving the first forward output and outputting a feedback output to the first summation module, wherein the first summation output equals the system input minus the feedback output. An error compensation module, having a compensation gain, is coupled to the first summation module for receiving the first summation output and outputting an error compensation output. The compensation gain is adjusted to provide the error compensation output with a predetermined value, such that an output error of a system output is substantially eliminated by combining the error compensation output with the first forward output.
