N2 - Delays can be a critical property of control systems, since they introduce a frequency-proportional phase difference. In some applications, it is desirable to speed up the dynamic behavior of such systems. In this paper, a control will be provided that couples a delayed system that has a nonlinear state space function and linear input/output functions with a non-delayed model using a Smith Predictor, and criteria will be determined for the system to provide the same output signal as the model. In an ideal case, it will therefore be possible to monitor the model instead of the system. It will be proven that the given structure induces a synchronized state and a measure for the suitability of the control for a monitoring problem will be introduced. The results are then validated based on an exemplary system.
