This study addresses the problem of global stabilisation by output feedback for a class of uncertain non‐linear systems whose output functions are not precisely known. To solve the problem, the authors first construct a new observer and then use the adding one power integrator technique to design a linear controller to globally stabilise the uncertain non‐linear system. It is shown that global exponential stability of the closed‐loop system is guaranteed by an appropriate choice of the design parameters.
