一、概述近年来,按偏差进行调节的反馈调节和按扰动进行调节的前馈调节的综合方式反馈——前馈调节,正在逐步研究应用于控制工业生产过程,并取得了比较显著的效果,在国外这种控制方式往往同反映过程机理的数学模型和电子计算机的应用联系在一起。针对我国工业发展的特点,如何推广应用新的控制规律,反馈——前馈调节,以提高大中小型工厂自动化水平,这个问题已提到日程上来了,在这一思想的指导下,我们开展了应用常规仪表实现反馈——前馈控制的研究工作,并应用在一些现场。下面所介绍的是在上海第三制药厂抗菌素生产中培养基连续消毒塔的温度反馈——前馈调节系统的应用
I. Overview In recent years, the feedback adjustment by deviation and the feedforward adjustment by disturbance adjustment feedback - feedforward regulation, is being gradually applied to control industrial processes and has achieved remarkable results, This type of control abroad is often associated with mathematical models that reflect the process mechanics and the use of electronic computers. In response to the characteristics of China’s industrial development, how to popularize and apply new control laws and feedback-feedforward adjustments to improve the automation level of large, medium and small factories has been mentioned on the agenda. Under the guidance of this idea, we carry out The application of conventional instruments to achieve feedback - feedforward control of the research work and applied in some sites. The following is introduced in the Shanghai Pharmaceutical Factory third antibacterial production of continuous media disinfection tower temperature feedback - feedforward regulation system
