摘要
研究机载平台稳定性优化控制问题,机载稳定平台主要用于隔离载机角扰动对探测装置视轴指向稳定造成的影响。四框架中的外框架组件随动于内框架组件,使探测装置视轴始终处于零位,以保证其最大的搜索视场。以某机载四框架稳定平台外俯仰位置随动回路为研究对象,根据PID控制器的外俯仰框架位置随动回路建立了数学模型,提出使用遗传算法对PID参数进行优化整定,利用MATLAB/Simulink软件对回路模型进行了仿真。结果表明,采用遗传算法优化后的PID控制器能够控制外俯仰框架更快速更平稳地随动于内俯仰框架,为机载平台稳定性能优化提供了参考。
An airborne stabilized platform is mainly used to isolate the effects on the detector LOS( Line of Sight) pointing stabilization, which are caused by the vehicles' moving. Outside - gimbals' frame fallows inside - gimbals' movements to make LOS always stay at zero - position to keep searching field biggest. Take the outside - gimbals' pitching position servo loop of one four - frame platform as the researching object, after modeling the outside - gimbals' pitching position servo control loop based on PID controller, this paper tuned PID controller parameters by u- sing genetic algorithm, and simulated the model by using MATLAB/Simulink. Simulation results show that the out- side - gimbal pitching frame can track the inside faster and more steadily while using PID controller which is opti- mized by genetic algorithm, which provides some advice for building an actual system.
