This study investigates the stabilisation problem for a class of inherently non-linear systems which are output-constrained. To solve such a control problem, a modified adding a power integrator approach is proposed. It is derived by combining standard adding a power integrator approach and a new barrier Lyapunov function together. The closed-loop system is asymptotically stable under the proposed controller. At the same time, the output constraints are satisfied. Simulations are performed to validate the effectiveness of the proposed control scheme.
