In this paper we investigate the problem of remote output stabilization via two channels time-varying delays. This problem arises when the control law is remotely implemented. The exchange of data between the controller and the system is done via two different transmission channels introducing time-varying delays with known dynamics. Assuming a known model for each of the time-delay dynamics, the work in [12] is extended to the case of two different delays appearing: (1) in the output measurement channel and, (2) in the transmission of the control law. This result is extended to output stabilisation by introducing a state observer built upon the delayed output of the plant. Simulation results are also presented.
