舰载光电跟踪伺服系统的建模与仿真

摘要

The ship - borne optoelectronic tracking servo - system using multi - loop serial composite control, on the basis of a typical three - loop control, the gyro stabilized loop is added to meet the requirements of the isolated ship shake,but it makes the loop design more complex. Multi - loop of servo system was modeled, and then the correction devices of current loop and velocity loop were designed. The system was simulated and analyzed by the use of computer simulation technology. The simulation results show the correctness of the established model, which is an effective simulation platform for the design of actual system parameters and the feasibility validation of advanced control algorithms.%舰载光电跟踪伺服系统采用多闭环串级复合控制,其在典型的三环控制基础上,加入陀螺稳定环,来满足隔离船摇的要求,但这使得环路设计较复杂.针对该问题,在建立主要部件数学模型的基础上,对伺服系统的各个环路进行建模,并对电流环、速率环的校正装置进行设计,借助计算机仿真技术对系统进行仿真分析.仿真结果表明所建模型的正确性,并且所建模型可为实际系统参数设计以及先进控制算法可行性验证提供一个有效的仿真平台.
