三阶工程最佳参数设计的新途径

A New way of Engineering Design for the 3rd--order Control Systems

本文导出了在线性响应范围内,实际三阶工程最佳参数系统的控制量和参考输入值上限的计算公式。在此基础上,从三阶工程最佳参数系统的等价结构出发,提出了三阶工程控制系统新的设计方法。它可以调节系统的时间常数至合理值,使所设计的系统较之按现行三阶工程最佳参数法设计的系统有较好的线性响应性能。

On the basis of author's research on the equivalent of what is called the 3rd-order optimum parameter system and development of the formulas for finding the limits in which the real system acts as a linear system, a new way is presented in the paper for engineering design of the 3rd-order control systems, which can adjust the time constant of the systems to a reasonable level so that they perform better than the current ones do in the linear operation.
