This paper presents the time delay filter (TDF) in which time delay is intentionally adopted in a filter and then time delay filter-based deadbeat control of a process with first-order plus dead time is implemented. The system stability is guaranteed with the Nyquist criteria and the PI controller is tuned by the frequency specifications. The time delay(More)
