This study is concerned with robust finite‐time stability and stabilisation of a class of switched positive systems. By using the multiple linear copositive Lyapunov function approach, sufficient conditions of finite‐time stability and finite‐time boundedness are constructed, respectively. l 1 ‐gain is used to analyse the disturbance attenuation performance of the systems, and a finite‐time weighted l 1 ‐gain is obtained under bounded exogenous disturbances. Then, the problem of robust finite‐time stabilisation of non‐autonomous systems with a weighted l 1 ‐gain is solved. All the proposed conditions are formulated in linear programming. Finally, two illustrative examples are given to show the validity of the theoretical results.
