Recent Research Highlight: Learning Control with Fading Channels
recent focus is learning control with fading channels. A fading channel
indicates the unreliable communication network that the transmitted
signal would suffer multiplicative randomness. Such randomness is
generally modeled by a random variable with its expectation away from
1; thus, the received signal is usually biased in the sense that its
expectation is not the original signal. Consequently, a correction is
necessary for the received signal before the following procedures. The
primary issue in this direction is how to correct the received signals.
If the statistics information (especially the mean) of the fading channel is known,
a direct correction can be made by multiplying the mean inverse to the
received signals. The design and analysis are given in [TSMC: Syst-2021].
We notice that the corrected input is involved with large disturbances,
which may significantly affect the dynamics of the plant. To address
this issue, we proposed an iteration domain moving averaging operator
for the received inputs. The results are elaborated in [TNNLS-2020].
Motivated by the averaging idea, we proceed to investigate how the
averaging techniques affect the learning and tracking abilities of a
conventional learning scheme, where the learning ability is reflected
by the convergence rate and tracking ability is reflected by the final
tracking precision. To this end, we studied three specific averaging
techniques, namely, moving averaging, general average with all
historical information, and forgetting-based average. The results
demonstrate that the forgetting-based average operator-based scheme can
connect the other two schemes by tuning the forgetting factor. The
results are provided in [TAC-2021].
If the statistics information is unknown, a promising approach is to estimate the mean of the fading channel. This idea is conducted in [TNNLS-2021a],
where an iterative estimation mechanism is proposed using a unit pilot
signal in each iteration. This mechanism provides necessary statistical
information such that the biased signals after transmission can be
corrected before being utilized.
All the above advances assume that the system information is available for the control design. If both system information and fading statistics are unknown,
a natural idea is to estimate them simulatenously. To this end, we
propose an error transmission mode and an iterative gradient estimation
method. Using the faded tracking error data only, the gradient for
updating input is iteratively estimated by a random difference
technique along the iteration axis. This gradient acts as the updating
term of the control signal. The results are summarized in [TNNLS-2021b].
