In this paper, the relationships of positivity and optimality for linear time - invariant systems are considered. First, the relationship of positivity and optimality for single-input single - output linear time - invariant systems is discussed by the frequency domain method. Next, for multivariable linear time-invariant systems, this relationship is discussed by the time domain method. The main results are as follows: The closed loop system formed by stable optimal state feedback is positive, its transfer function...

In this paper, the relationships of positivity and optimality for linear time - invariant systems are considered. First, the relationship of positivity and optimality for single-input single - output linear time - invariant systems is discussed by the frequency domain method. Next, for multivariable linear time-invariant systems, this relationship is discussed by the time domain method. The main results are as follows: The closed loop system formed by stable optimal state feedback is positive, its transfer function matrix is positive real. Conversely, if the open loop transfer function matrix is positive real, then the closed loop system obtained by negative unity output feedback is stable and optimal. Finally, from the discussion of the relationships of positivity and optimality we showed that the stable gain margin of optimal control systems is infinite.

This paper presents a new exact method for the detection of edges in digital grey level imagery. This method performs expanding and compressing algorithms on the binary graph of classification of the original image in order to delete the additive white Gaussian noise and other disturbances, and to extract a coarse boundary of object. Then, within the neighborhood of this boundary, we trace the edge pixels based on an isotropic gradient operator and orientation information. Furthermore, we estimate the object's proportion of each edge pixel, using a local optimal proportion estimation operator (so called subpixels segmentation). Combining the proportion values and forword orientation of edge, we compute intersections of boundary curve and each edge pixel. After geometric correction of all intersections, we output the smooth curve of object edge and its area, using automatic computer graphic techniques. Finally, through experimental analysis of analog data and actual image data by using above process, we show that this method provides us an optically better edge than any others which output an edge by taking pixel as a unit, that it also gives us a more accurate position of boundary and area of object. This has a quite significance for combining automatic graph techniques with image process techniques, automatic mapping of remote sensing data, large scale mapping of low resolution data image, and for application fields which demand sub-pixel accuracy area survey of objects.

本文给出一种较精确的光滑边界探测方法。首先对经过分类的二值图像执行生长与压缩运算以消除高斯白噪声并抽取目标粗边界;然后在粗边界内,依据一种全向梯度算子和方向信息跟踪边界元素;对这些跟踪得到边界元用一种局部比例估计算子估计各个边界像元上目标所占的比例;结合比例值和边界的前进方向信息计算边界曲线与边界像元的交点;对这些交点执行几何精纠正后用绘图机结合曲线光滑方法输出目标的光滑曲线及其面积。最后通过对模拟数据和实际图像数据的试验分析,表明本文给出的方法比以像元为单位输出的边界有更好的视觉效果,并给出更精确的边界位置与目标面积。这对于自动成图技术与图像处理技术的结合,对于遥感图像数据的直接成图输出,对于要求分像元精度量算目标面积的应用领域,对于低分辨率数字图像的大比例尺成图都有一定意义。
