摘要
舵机带宽是舵机动态特性的一个重要参数,可根据其动态数学模型求取,模型常通过系统辨识得到,但传统的辨识方法有局限性;通过分析支持向量机(SVM)应用于线形回归的基本原理,提出将其用于舵机的系统辨识;利用支持向量机对测试数据进行处理,实现了对舵机的系统辨识,得到舵机模型而求其带宽;实践结果表明,基于SVM的系统辨识有很高的辨识精度,SVM用于舵机带宽测试,效果不错,是一种有前途的方法。
The bandwidth is an important parameter of rudder＇ s dynamic behavior and can be obtained from rudder＇ s mathematical model. Traditional methods of system identification can get the model, but can＇ t avoid any localization. Support vector machine has capacity of linear regression and its usage for identifying the model of rudder is introduced. Data processing based on support vector machine （SVM） is presented. It implements system identification for rudder＇s behavior, the bandwidth can also be obtained. The results indicate that system identification based on SVM has high precision and good performance for testing the bandwidth of rudder.
