| 1. | With pseudorandom binary sequence as inspiriting signal , feedback data is collected and time - domain and frequency - domain characteristic of the steering gear is analyzed . according to the results , system delay is determined . applying predictive error identification method , by comparing the different order model , model structure and parameters of the steering gear is determined 以伪随机二进制序列为激励信号,收集了反馈数据;利用收集的数据,对舵机进行了时域和频域特性分析;并以此为参考,确定了系统的延时量,应用预报误差的辨识方法,通过不同阶次模型间的比较,从而确定了舵机模型结构及参数。 |
