Abstract

This paper aims to provide a global sliding mode control (GSMC) method using nonlinear extended state observer (NESO) for thermal-structure test (TST). Firstly, the designed control method adopts NESO to observe the internal and external disturbances of the system. Then, the nonlinear global sliding mode surface is constructed to improve control accuracy, speed up convergence and reduce the chattering phenomenon. Finally, the effectiveness and superiority of the proposed method compared with existing control methods are verified by comparison of simulation and experimental results.
