This paper considers the application of a differential flatness based method for the derivation of the linearising state for input-state feedback linearisation. It gives the details of the application of this technique in the computation of the flat output for a third order single machine infinite bus system (SMIBS) employing the one axis model of the synchronous generator. The corresponding linearised model was derived and a nonlinear controller designed for the asymptotic stabilisation of the single machine infinite bus system (SMIBS). The dynamic behaviour of the third-order plant equipped with the derived nonlinear controller is then illustrated by simulation.
