variety control meaning in English

品种控制

It ' s a driving force and also a challenge to control in both theory and technology due to the more and more severe specifications imposing on it . a variety control theory have been developed , however , with limited performance in practical applications , especially in term of the relatively lower response speed when used in those machines which run fast . therefore , it is necessary to develop a new self - tuning algorithm for fast running plant of uncertainty so as to set theoretical base for controller design
在科技飞速发展的今天，各种新设备、新工艺的出现促进了控制理论的发展，同时也对控制技术提出了越来越高的要求，虽然已有许多旨在提高控制性能的不同的控制理论，但由于其各自的局限性，在应用中仍然存在许多问题，特别是对于运行速度较快的机械设备等，其响应时间往往不能达到要求，因此，有必要开发一种新型、快速、能够适应快速运行或变化的对象或过程的自调节算法，以为控制器的开发作好理论支持。
