  In the present work, an embedded PI controller is designed for speed
regulation of DC servomotor over a wireless network. The embedded controller
integrates PI controller with a proposed time-delay estimator and an adaptive
digital Smith predictor for its real time operation, which is the novelty of
the work. The real time or rather online operation of the developed embedded
controller over wireless network is possible mainly due to the contributions in
terms of proposing a new empirical formula for time-delay estimation, viable
approximation of time-delay, discretization scheme in developing the proposed
adaptive Smith predictor. The proposed embedded design validates that the
deterioration of control performance due to random network-induced delay are
mitigated in real time. The embedded controller is designed and tested for a
short-range of 100 meters, and wireless technology chosen is suitable for
biomedical applications.
