| Summary |
This manuscript presents a simple scheme to improve the
performance of a feedback control system that uses power line channels for
its feedback loop. The noise and attenuation of power lines, and thus the
signal to noise ratio, are known to be cyclostationary. Such cyclic features
in the channel allow us to predict virtually error free transmission instants
as well as instants of high probability of errors. This paper introduces and
evaluates the effectiveness of a packet transmission scheduling that collaborates
with a predictive control scheme adapted to this cyclostationary environment.
In other words, we explore the cooperation between the physical
and application layers of the system in order to achieve an overall optimization.
To rate the control quality of the system we evaluate its stability as
well as its ability to follow control commands accurately. We compare a
scheme of increased packet rate against our proposed scheme which emulates
a high packet rate with the use of predictive control. Through this
comparison, we verify the effectiveness of the proposed scheme to improve
the control quality of the system, even under low signal to noise ratio conditions
in the cyclostationary channel. |
