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

尽管在用于不稳定的一阶加死区时间（UFOPDT）过程的死区时间补偿器（DTC）领域取得了许多进步，但通常还是手动进行调整。因此，本文针对用于UFOPDT流程的DTC提出了简单的调整规则。规则基于相对死区时间，所需的闭环时间常数和可实现的鲁棒性。此外，由于实际的实现总是在离散时域中，因此提出了一种选择UFOPDT过程采样周期的方法。文献中的四个仿真示例用于说明该方法的优点。另外，进行了带有螺旋桨摆的实验，以证实在控制具有停滞时间的实际不稳定过程中的这种优势。
