基于双态混沌PSO的机载激光通信视轴稳定控制

Chaos Binary-State PSO of optical axis stabilization control for airborne laser communication

机载空间激光通信视轴稳定是激光通信链路建立的前提。在视轴稳定平台中应用自抗扰控制方法取得了良好的控制效果,但自抗扰控制需调整参数众多且缺乏规范的调整手段。针对自抗扰控制调参难的问题,本文提出了一种利用双态混沌粒子群算法优化自抗扰控制参数的方法。仿真结果表明,与PSO-PID控制方法相比,该方法具有更快的响应速度,更强的抗干扰能力和更好的鲁棒性。

The premise of the laser communication link establishment is the Optical axis stabilization in space laser communication.Good control effect is achieved by applying the ADRC in the optical axis stabilization,but,ADRC needs to adjust a large number of parameters and lack of standardized adjustments.In view of difficulties in adjusting the parameters of ADRC,this paper proposes to optimize ADRC parameters by using Chaos Binary-State Particle Swarm Optimization.Compared with the PSO-PID control method,the simulation experiment results show that the Chaos Binary-State Particle Swarm Optimization ADRC has better fast response speed、stronger disturbance rejection ability and stronger robustness.
