Tuning rules for unstable dead-time processes

Despite many advances in the field of dead-time compensators (DTCs) for unstable first-order plus (UFOPDT) processes, tuning, general, is manually carried out. Therefore, this paper proposes simple tuning rules a DTC intended to UFOPDT processes. The are based on relative dead time, desired closed-loop time constant, and achievable robustness. Besides, as practical implementation always discrete-time domain, method choose sampling period processes presented. Four simulation examples from literature used show advantages proposed method. In addition, an experiment with propeller pendulum performed confirm such control real process time.
