Event-triggered sliding mode control for uncertain systems with multiple disturbances

A new event-triggered sliding mode anti-disturbance (ETSMAD) control scheme is presented for the uncertain linear systems encountered by multiple disturbances containing the modelled unmeasurable disturbances and unmodelled disturbances. On the sliding mode reaching stage and sliding stage, different event-triggered programmes are developed to reduce the communication transmission load between the system and controller. The SM control law based on the ET programme is established to achieve the compensation and suppression of the modelled unmeasurable disturbances and unmodelled disturbances, respectively. Meanwhile, the criteria are formed to ensure the robustness of the system. The efficiency of the established ETSMAD control strategy is confirmed by a turbofan system example.
