| 摘 要： | 采用机理建模方法对舵机系统进行数学建模受到的限制比较多,如LVDT传感器、功放模块等非线性环节。采用实验建模的方法,利用试验测得的电动舵机的频率响应曲线来辨识出舵机系统的数学模型。经过仿真分析,比较得出采用的实验建模方法所建立的模型误差更小、更接近实际系统。

| Abstract: | It's many limit to build the mathematic model of elctric actuator by mechanism for its nonlin- earities,such as LVDT sensor and nonliner energy amplification module.It adopts experiment method and use the frequency response curve build up the mathematic model of actuator.The simulation results demonstrate that the model which is identifacted by experiment is more opproach the actual system and the error is smaller. |
