摘要
船载光电成像稳定平台为舰船在高速及恶劣海况下进行光电成像侦察提供了基础条件,近年来光电平台结构越来越复杂,要求的稳定精度越来越高,为了提高平台稳定精度,必须选择合适的结构方案并进行合理的控制回路设计;文中介绍了稳定平台的几种框架形式,从稳定原理方面分析了各自的特点,指出三轴稳定平台系统是最佳的选择方案,在此基础上对三轴自主稳定平台伺服稳定控制回路进行了设计,仿真结果表明在选择合适的超前-滞后网络后,系统的隔离度达56db,稳定性能满足使用要求。
Shipboard opto-electronic Imaging stabilized platform provides the basic condition for the ship under the high speed and bad sea condition. Recently its structure is more and more complex, and the demand of stability precision is more and more higher. In order to improve the stability precision of opto-electric platform, it must choose right structure scheme and design rational control loop. In this paper, several frame shapes of stabilized platform are introduced. The each characteristics are studied from the stabilization principle, this paper points out the three-axis stabilized platform is the best choice, and designs its control loop. The simulations have shown its stability performance fulfill application requirements.
