Abstract: | The error performance of a linear time-invariant plant, remotely controlled with constant-gain state feedback from a coded digital communications link, is considered. The effects of finite information rate, reliability, and delay are examined. While nonzero code transmission delay is generally deleterious to control system performance, it is shown that if the sampling period is specified, then block coding within each sample period may be beneficial. Numerical results are given for the case of a scalar plant |
