A Method of Comparative Evaluation of Control Systems by the Set of Performance Measures

Abstract

It was proposed a method of comparative estimation of process control loops based on a complex of direct and indirect performance measurers taking into account stability margins. It was presented a comparison algorithm for complex performance parameter considering the influence of stability margins of a control loop on its properties. Features of the method of comparative estimation of process control systems performance have been considered as an example for the closed loop feedback control system with PI controller (4 variations) and the second order plus transport delay plant.

Section method for real-time monitoring of the surface shape of the laser beam radiation spot

“…4. Comparative analysis shows that the proposed methods make it possible to measure the coordinates of the center of laser images with an accuracy of determining the anchor point of at least 1-2 decomposition elements, which in accuracy exceeds the known ones, for example, based on the determination of the center of mass using moment signs or similar [9][10][11][12][13][14][15][16][17][18] , on average in 1.5 times.…”
