Target Feedback Loop/Loop Transfer Recover (TFL/LTR) Controller applied to Networked Systems susceptible to Communication Losses

摘要

This paper presents a fault-tolerant controller applied to a system containing communication channels susceptible to data loss. The proposed approach is based on the Target Feedback LoopLoop Transfer Recover compensator, capable of dealing passively with the general or intermittent loss of the actuator or sensor signal. In this scenario, the controller structure and the calculations necessary for its design are described, as well as the mathematical modeling strategies of the data transfer faults. By employing the designed compensator, the results obtained in the simulations presented in the paper show that the system response remains stable and with proper reference tracking, even against the data loss in the actuator signal.
