A multiple hierarchical structure strategy to quantized control of Markovian switching systems

This paper deals with the issue of nonstationary quantized control of Markovian switching systems. A more general networked Markovian switching system is exploited, where the randomly occurring PDs and a mode-dependent logarithmic quantizer are involved. Different from existing works, a novel nonstationary quantizer is introduced by utilizing a multiple hierarchical structure strategy. On the basis of mode-dependent Lyapunov functional, a sufficient condition is formulated and quantized controller gain is designed. In the end, the effectiveness of the theoretical results are proved by an automotive electronic throttle model. (C) 2020 Elsevier Inc. All rights reserved.
