RTD-A controller has recently been proposed as an alternative to the proportional-integral-derivative (PID) controller for control of single-input single-output systems. The RTD-A controller maintains the simplicity like the PID controller, has predictive capabilities like model predictive controller, and allows easier tuning of the controller parameters to achieve desired closed-loop performance. The available tuning rule for RTD-A controllers are aggressive, and their application to practical problems can be difficult, In this paper, a block diagram representation of the RTD-A controller is developed. It is shown that the RTD-A controller can be viewed as a generalized analytical predictor augmented with noise and set point filters. On the basis of the block diagram representation, semianalytical tuning rules are proposed for the RTD-A algorithm. It is shown that the RTD-A controller tuned using the proposed rule provides reasonable performance for a wide class of processes including inverse response and delay-dominant processes.
