摘要
通过对步进电机加螺旋装置、电液伺服系统、电动推杆、直流比例电磁铁和步进液压缸五种控制系统进行比较,电液伺服系统简便易行,控制精度高,响应速度快,使用寿命长,成本相对较低,适合在农业生产中推广应用。
Through the comparison of five kinds of control systems, that is, the stepping motor and screw device, electro-hy- draulic servo system, electric putter, DC proportional electromagnet and stepping hydraulic cylinder, the result shows that the electro-hydraulic servo system is more simple and convenient, with high precision, fast response, long service life, and relative- ly low cost, suitable for application in agricultural production.
