“…Although the wireless scheme is applicable up to zero speed, in this paper, the lower speed limit of 20 r/min (∼0.3333 Hz) was used because of the lower bandwidth limitation of the analog RF transmitter. Our recent work in [15] with complete digital implementation overcomes this limitation.…”

Abstract-In this paper, we demonstrate the feasibility of controlling the speed of an induction motor using a wireless position feedback over an RF link, and compare its performance under dynamic-and steady-state conditions with those obtained by using a wire-based position feedback control. The wireless scheme precludes the need for the cable that feeds the position from the sensor to the controller, thereby minimizing feedback noise pickup and cost for some applications. It also raises the possibility of using a low-resolution, low-cost sensor, which, along with the use of simple estimation algorithms, may potentially provide an alternative to or backup support for conventional position sensorless control for a wide range of motors and speeds. Further, using a composite Lyapunov-function-based approach, we determine the effect of time delay (due to wireless communication) on the stability of the overall system. Index Terms-Composite Lyapunov function, induction motor, linear matrix inequality, piecewise nonlinear system, position feedback, speed control, wireless network control.

“…This is the basis for the constant back-off window assumption in our model. Unlike the Markov models in [15][16][17]19] which are employed at each node, our proposed model [29] is for the complete network. The key advantage of our approach is reduced order network model as compared to node based modeling approaches.…”

We have developed a three-state discrete-time Markov-chain model for the performance evaluation of contention-based medium access control (MAC) protocol. The proposed Markov-chain model is then used to analyze the carrier sense multiple access (CSMA) type MAC protocol for its delay and throughput characteristics with and without transmitter power control. Using simulations, the conditional capture probability (p cap ), which gives a measure of the effectiveness of transmitter power control due to the capture effect, is quantified and experiments are performed to validate these simulated data for the p cap . To analyze the effect of transmitter power variation, the Markov-chain model is modified by incorporating the p cap . Numerical results show significant throughput as well as delay performance improvement using transmitter power control.
