摘要
以无人机发射平台为研究对象,通过对系统原理的详细分析,采用改进的PID增量控制闭环方式实现系统功能,来对无人机发射平台实现多状况下的快速、高精度调平。在建立好合理的平台液压调平模型后,利用AMEsim系统建模软件进行仿真分析,取得了很好的效果,并对比例换向阀与液压缸进行了详细的动态特性分析和研究工作。仿真结果表明,在前后支腿间距4340mm的条件下,达到调平精度±0.2°,所建立的系统仿真模型可适应发射平台的快速、高精度调平要求,实现了系统的跟随功能,满足系统的动态响应要求。
Taking the UAV launch platform as the research object, through the detailed analysis of the system principle, the improved PID incremental control closed-loop method was used to realize the system function, so as to realize the rapid and high-precision leveling of the UAV launch platform under multiple conditions. After establishing a reasonable hydraulic leveling model of the platform, the AMESim system modeling software was used for simulation analysis, and good results were achieved. The detailed dynamic characteristics analysis and research work of the proportional directional valve and hydraulic cylinder were carried out. The simulation results show that under the condition of 4340 mm distance between the front and rear legs, the leveling accuracy is ± 0.2 °. The system simulation model can meet the requirements of quick and high-precision leveling of the launch platform, realize the following function of the system, and meet the dynamic response requirements of the system.
