Sliding mode based on-line drag estimation of a simulated aircraft over a wireless network

On-line parameter estimation over a wireless network based on sliding modes for a high fidelity simulation of a four engine transport aircraft is described in this paper. An approach using a sliding mode observer involving a second-order sliding mode `super-twisting´ injection signal to estimate changes in the drag coefficient is proposed. A peer-to-peer wireless network is considered in which one of the computers generates data from a high fidelity four engine transport air-craft model in real-time, which represents a `virtual transport aircraft´, and the other computer processes each data package to carry out on-line estimation of the drag coefficient.
