control engineering practice meaning in English

控制工程实践

Proportional - integral - derivative ( pid ) is one of the most widely used control strategies in the process control engineering practice
在控制工程实践中， pid控制是应用最为广泛的一种控制策略。
However , the artificial methods for tuning pid parameters are so far applied commonly regardless of in the domestic or overseas process control engineering practice , which cause the pid tuning job extremely time - consuming and can not assure of the best control system performances consequently , particularly for these time variant processes
然而，至今控制系统的pid参数整定工作无论是在国内还是在国外的控制工程实践中，主要采用的还是人工整定法。这使得pid参数的整定工作不仅费时，而且难以保证控制系统性能最佳，尤其是对于被控对象特性随工况发生变化的系统， pid参数人工整定法更不能满足系统的要求。
