“…In practice, a MagLev system may be subjected to both matched and mismatched uncertainties [40]. The matched uncertainties are mainly derived from the source voltage fluctuation or the coil parameters variations, existing in the same channel as the control input [41]. The mismatched uncertainties are caused by the modelling errors (linearisation errors) and the unmodelled terms of the complicated dynamics of the electromagnet, existing in different channels from the control input [42].…”
