张力伺服系统 meaning in English

tension servo system

Heavy interference ， changeable variables and load are the characteristics of film supply system and film receipt system . resolutions for these problems are emphasized in this paper . as usual , the effective method to solve the heavy interference in low frequency and the changeable load is compound control for disturbance compensation
供片、收片张力伺服系统具有变参数、变负载、强扰动的技术特点，解决这些问题是本论文的重点内容。通常情况下，在解决低频强扰动、变负载问题方面，最有效的方法是采用按扰动补偿的复合校正方式。
Film transmission machine consists of film supply system ， film receipt system and film measuring system . both film supply system and film receipt system are tension servo systems . film measuring system is system of controlling film length ， this three systems are independent and relative one another . film measuring operation of film measuring system disturbs both film supply system and film receipt system as an extra - interference and it is very heavy
等量牵引式输片机构由三部分组成? ?供片系统、收片系统和量片系统，供片、收片系统均为一个张力伺服系统，量片系统是一个画幅控制系统。三个系统各自独立又彼此联系，量片系统的量片操作对供片、收片张力伺服系统是外来的干扰，且扰动力很大。
