环境对稳定平台运动性能影响的仿真技术研究

环境因素的动态变化将会对车载/舰载平台的稳定性能产生影响。通过综合自然环境SNE的建模原理和方法对影响车载/舰载平台稳定性能的环境因素（主要包括地形、海洋以及大气因素中的风）进行建模;结合PID控制理论,对稳定平台的控制系统进行建模;将MATLAB与开源三维渲染引擎OGRE结合构建车载/舰载平台运动受环境影响的仿真系统。通过改变环境属性值,对比分析不同环境情况下的平台运动稳定性能。仿真结果表明,将SNE的影响作用于平台稳定性仿真系统中,是可信地评价稳定平台控制系统性能的重要保障。

Simulation technology study on the effects of environmental factors on the stable platform motion performance

Vehicle/ship-load platform stabilization performance is affected by dynamic changes of environmental factors.Based on modeling principles and methods of synthetic natural environment（SNE）,models of environmental factors（mainly include topography,atmospheric factors of ocean and winds） which affect vehicle/ship-load platform stabilization performance were established.Combined with PID control theory,a mathematical model of the stable platform＇s control system was created,and a simulation system was built based on MATLAB and open source 3D rendering engine OGRE.By changing the environment property values,the platform motion performance under different environmental conditions was compared and analyzed.The simulation results showed that to simulate the effects in the system is important to credibly evaluate performance of the stable platform＇s control system.
