Abstract :
In this paper, we apply HARQ to a wireless feedback control system for realizing high reliable communication. In the wireless control system, since the quantity of state of a control system influences the stability of the system, we propose the new HARQ system which determines a code rate and retransmission judgment according to the quantity of state. As a result, proposal HARQ solved the problem of the overhead by coding and improved control quality compared with HARQ-TypeI.
