摘要
阐述了所研制的新型全数字式电液调速器,采用较新的电液比例技术与计算机技术相结合组成的电液比例随动系统的结构的方案的研究,及其步进电机控制电路和程序的设计,这种调速器与传统的电液调速器相比,具有定位精度高,抗污染能力强,可靠性高等特点,是一种具有广阔前任的新型高速器。
This paper deals with a new-type full-digital electro-hydraulic speed governor and makes a study of the structure scheme of electro-hydraulic proportion servo system,a product of up-to-date electro-hydraulic proportion technique and computer technology combine and its de sign of step-by-step motor control circuit and programme.Compared with the traditional ones,this type of electro-hydraulic speed governor possesses such characteristics as highly accurate posi tioning,strong anti-pollution capability,high reliability,etc,and hence a new-type speed gover nor holding a vast prospect for development in the future.
