The mathematical mod els based on the assumed modes method and a dosed loop velocity feed back control law are developed to describe the fiexural vibration dynamic behaviors 引入速度負反饋形成閉環(huán)控制,對被動控制和主被動控制的控制效果進行了分析比較。
Feed back control base on nonlinear pid with self - adjust parameter and feed forward control base on experience model are employed in the practical application . the realization of this control system and its result are introduced in this paper . because the process of the reaction is complicated , it ' s difficult to model for it 在對中和過程自動控制算法的探索中,采用了非線性參數(shù)自整定控制和基于模型的前饋控制,本文介紹了這種控制系統(tǒng)的實現(xiàn)和現(xiàn)場控制效果,由于中和控制過程的模型極其難以確定,反應過程變化復雜,因此基于模型的前饋控制無法對ph值和流量值的波動進行有效的補償。
