| Summary |
In wireless feedback control systems, it is important
how to reduce packet losses. If channel coding is
used, packet losses may decrease. However, coding redundancy
decreases the packet transmission rate under the same bit
rate, so that the control systems become more affected by
disturbances. To improve the quality of the control systems,
the channel coding should be used adaptively based on packet
losses and disturbances. In this paper, we propose an adaptive
coding scheme based on the quality of the communication layer
and the control (application) layer. In this scheme, the channel
coding is used adaptively to minimize the tracking error of the
controlled plant. We show that the proposed adaptive coding
scheme improves the reference tracking performance of the
control system compared with that with fixed rate coding. |
