油滯后現象 的英文怎麼說
中文拼音 [yóuzhìhòuxiànxiàng]
油滯后現象
英文
oil hysteresis-
Secondly, during the braising offline temperature control loop of the oil production - lixiviating procedure, the controlled object, which is hard to build the extract model, has the characteristics of large inertial, big time - delay. the control strategy of the combination of fuzzy logic arithmetic and normal pid arithmetic is introduced in this paper, the basic principle and actualization method of fuzzy - pid are analyzed. the design model is simulated in matlab and the result proves good control performance
其次，玉米油生產浸出工序的蒸脫機溫度控制迴路中，被控對象具有難以建立精確的數學模型，且具有大慣性、大滯后的特點，研究運用模糊控制演算法和經典pid控制演算法相結合的控制策略，分析了模糊pid控制演算法的原理和實現方法，並運用matlab軟體對設計的系統進行模擬，模擬結果表明，達到較好的控制指標。For example, petroleum chemical engineering systems and metallurgy systems can be modeled as time - delay systems for their content lag and transmission delay. in addition to these, because of transmission process, large - lag links and complicated on - line analyzer etc, a large number of industrial processes ( in metal engineering, chemical engineering systems, biomedical systems and so on ) can be modeled as time - delay systems
基本上是不可避免的，大慣性環節、傳輸過程、復雜的在線分析儀、石油化工和冶金工業過程中的容量滯后和傳輸延時等不可避免地會導致滯后現象，而這些滯后特性往往會嚴重影響控制系統的穩定性以及系統的性能指標，甚至使系統不穩定性。
