Abstract

In a wireless structural control system, a linear quadratic Gaussian regulator, under measurements loss, is used to limit the RMS structural response to natural hazards. The analysis shows the dependence of the state estimation error, and corresponding control performance, to the packet error probability and transmission delay. These metrics are studied for two communication access techniques: code-division multiple-access (CDMA) and time-division multiple-access (TDMA). By simulating a 9-story benchmark building with real earthquake inputs, it is shown that CDMA scheme performs better with few sensors scenario due to the low latency, however, more sensors may decrease the closed-loop performance due to high delay (TDMA) or high lost rate (CDMA).
