Abstract :
This paper investigates adaptive fault-tolerant H∞ power and rate control for wireless networks. Based on the new joint power and rate control model, an indirect adaptive fault-tolerant controller via dynamic output feedback is presented for transmitter fault compensations. The adaptive H∞ performance of the closed-loop system is analyzed based on the linear matrix inequality (LMI). Simulation results are given to demonstrate the effectiveness of the proposed controller.
