通过数值算例说明，机械控制系统的设计具有一定的分离性。特别地，我们指出伺服跟踪系统的控制带宽与开环传递函数呈现正真实度的频率范围密切相关，而动态输出反馈控制器可以通过合理的控制努力来实现。用线性矩阵不等式来表示有限频率的正实性质。最后，利用强大的凸规划技术，提出了设计具有这种性质的机械系统的系统程序。
This paper shows, by a numerical example, that there is a certain separation property in the design of mechanical control systems. In particular, we point out that the control bandwidth of a servo-tracking system, achievable by a dynamic output feedback controller with reasonable amount of control effort, is closely related to the frequency range where the open-loop transfer function exhibits positive-realness. A finite frequency positive real property is characterized in terms of linear matrix inequalities. Finally, a systematic procedure for designing a mechanical system having such property is proposed, utilizing powerful convex programming techniques.
