摘要
分析了无人机电动舵机伺服系统各组成部分的原理,利用Matlab/Simulink工具建立了整个舵系统数学模型,并对舵系统的输出力矩、转速以及位置的动态响应进行了仿真。之后建立了舵系统的传递函数模型,对舵系统的稳定性指标进行了仿真分析。结果表明通过两种方式对电动舵机回路进行建模分析,有利于更全面准确的了解系统动态特性,减少了舵系统设计难度,增强了系统的可靠性。
The principles of the components of UAV Electromechanical actuator servo system are analyzed.With the use of Matlab/Simulink tools a mathematical model of the rudder system is created.And the dynamic responses of output moment,speed and location are simulated.Then the transfer function model of rudder system is established,and the stability indicators are simulated.The results indicate that creating models in two different ways are benefit for learning dynamic characteristis of the system comprehensively and accurately,reducing difficulty of rudder system design and increasing system reliability.
