Observer based robust H/sub /spl infin// control design for rail guidance systems

This paper proposes an optimal and a robust control design approach for position sensorless active rail vehicle guidance control design. As the first step an observer based H/sub /spl infin// state-feedback control of a wheelset system is designed. After that, the effect of parameter uncertainty on the self sensing control of a nonlinear rail wheelset system is investigated and a new controller is designed by including the modeling of parameter uncertainties. The simulation results are satisfactory and in good agreement with previous work.
