Industrial Automatic Control Systems and Controllers Annotation << Back Loop tuning in functional subsystems of thermal engineering control systems using cyber-technologies Akchurin D.Kh., Khromov N.N. A PID controller tuning procedure is proposed that does not require any intervention into process operation and enables statistical estimation of its variables. The paper shows that the procedure allows to monitor both plant identification accuracy and controller settings. E-mail: avtomat@pnzgu.ru
