Abstract:
This brief investigates the output-feedback control problem with redundant channels, in which the output measurements may suffer from the Markov analog fading when transmitting through the independent primary channel and redundant channels. The actual channel mode obeys a two-state time-homogeneous Markov chain, and the expectation of fading amplitude in the good mode is much higher than the one in the bad mode. The mode detectors are employed to estimate the status of both the primary and redundant channels, by which the better measurement signals may be selected for the controller. Thus, a token-dependent output-feedback controller is constructed, and then, the stability condition is obtained via the actual mode-dependent Lyapunov function method. Finally, the proposed output-feedback control scheme is applied to an operational amplifier (OPA) circuit under the hidden Markov analog fading channels.
