This study investigates decentralised fault-tolerant finite-time stabilisation problem for a class of interconnected non-linear systems with gain fault in each actuator. Each subsystem of the interconnected system is with lower-triangular structure. In the procedure of controller design, unknown faults of the system are eliminated via robust control technology. Then, based on finite-time Lyapunov stability theorem and recursive design algorithm, decentralised state feedback controller is proposed to guarantee global finite-time stabilisation of the interconnected system. Finally, two simulation examples are given to verify the effectiveness of the proposed design method.
