Fault tolerant control of two tanks system using gain-scheduled type-2 fuzzy sliding mode controller

To save the robustness of type 2 fuzzy logic control technique and to avoid high energy consumption that represents sliding mode (SMC) technique, without failing performance system, we propose a new fault tolerant method based on gain-scheduled with interval (FTCGST2FSMC) applied hydraulic system (two tanks system) an actuator fault. The proposed scheme avoids difficult modeling, due chatter effect SMC, guarantees stability studied by Lyapunov system. gains SMC controller are modified changed adaptation logic, used improve when is added, FTCGST2FSMC has been compared controller. results obtained confirm this method, in presence effect.
