Simplified dead-time compensator for multiple delay SISO systems

•This paper presents a DTC structure for SISO systems with multiple delays.•Primary control is taken in the feedback path through two FIR filters with simple tuning rules.•The overall control design presents anti-windup behavior.•The technique is able to deal with stable and unstable systems.

This paper presents a dead-time compensation structure able to deal with stable and unstable multiple delay single input single output (SISO) systems. The proposed method aims to simplify the primary controller by replacing it for FIR filters placed at the feedback path. Such modification reduces the total number of parameters to be tuned which facilitates the overall design in comparison with other primary controllers normally considered. Simulation results show a better performance for the proposed control approach compared with other dead-time compensator (DTC) recently proposed in the literature.
