The algorithms of output controllers design are proposed for linear scalar plants, that ensure the desired or attainable values of oscillation index and of degree of stability, determining the settling time. Both modal control and H-approach are used in the design procedures. Examples are constructed, demonstrating that striving to provide the degree of stability that is much greater than the distance from the nearest left zero of the plant transfer function to the imaginary axis (even for the minimum phase plants) leads to the quite small gain and phase stability margins, that is unacceptable in practice.

给定振荡指数标量控制器的设计:模态和H∞方法

提出了针对线性标量设备的输出控制器设计算法,该算法可确保所需的或可达到的振荡指数和稳定性值,从而确定稳定时间。两个模态控制以及ħ -approach在设计程序中使用。通过构造示例,表明努力提供比从植物传递函数的最接近的左零到虚轴(即使对于最小相位的植物)的距离大得多的稳定性会导致非常小的增益和相位。稳定余量,这在实践中是不可接受的。
