A Dead-Time Compensator With Dead-Beat Disturbance Rejection Response

This work proposes a dead-time compensator (DTC) with dead-beat disturbance rejection response. The proposed strategy is based on the simplified dead-time compensator (SDTC) because of its simplicity and good performance. A new robustness filter to obtain a dead-beat disturbance rejection response is proposed. The dead-beat robustness filter is then implemented using complex conjugate poles and an additional zero. Simulation results comparing the proposed methodology with the SDTC show that the new obtained controller presents faster disturbance rejection with finite time response.
