利用镜像映射技术，给出了具有一个或多个正极点的高阶不稳定时滞过程的一般方案。采用奈奎斯特标准来建立一套系统的方法来调整参数。稳定参数区域可以保证预先指定的稳健性指标。在该方案中，基于全极点Padé近似模型设计了控制律。首先将不稳定过程映射到最小相位系统，然后通过闭环增益成形算法(CGSA)获得实际控制。其优点是设计过程简洁，并能获得良好的抗扰性能和鲁棒性。最后，用三个被广泛引用的实例说明了该方法的有效性。
In this note, a general scheme is proposed for the high order unstable delay process with one or more positive poles, using the mirror mapping technique. The Nyquist criteria is employed to establish a systematic methodology to tune the parameter. The stabilizing parameter region could guarantee the prespecified robustness specification. In the scheme, a control law is designed based on the all-pole Padé approximated model. The unstable process was first mapped into a minimum-phase system, and the actual control is obtained by the closed-loop gain shaping algorithm (CGSA). The advantages are that one has a concise design procedure and can achieve good performance such as disturbance rejection and robustness. Finally, three highly cited examples are used to illustrate the effectiveness of the proposed method.
