虚拟复合轴伺服系统的等效复合控制方法
An equivalent compound control based on a suppositional compound-axis system
摘要
Abstract
A suppositional compound-axis system was generated for an ordinary electro-optical tracking platform without a fast-steering mirror based on the principles and rules of an equivalent compound-axis system. It was composed of a suppositional platform, suppositional detector, and actual tracking platform. Its system structure was completely the same as a compound-axis system. The suppositional detector arithmetic and object characteristics of the suppositional platform were calculated so that the suppositional system could be realized and an equivalent compound control method could be established. At last the traditional PI control, PI with velocity delay compensation,and the two-dimensional PI control were analyzed and compared. During simulation, tracking precision of a two-dimensional PI control based on the equivalent compound control was 16 times higher than that of a PI control and 3.7 times higher than a PI control with velocity delay compensation. The steady state error was less than 1′ when the target moved at a maximum rate of 10°/s angular velocity with a maximum of 5°/s2 angular acceleration.关键词
