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.
