For the active fault-tolerant control method of non-linear system with multi-failures, the identification algorithm of the improved CMAC based on balanced learning is used to estimate faults function in this paper. The fault - tolerant control is realized by utilizing the effective control law reconfiguration strategy based on sliding model control algorithm. Finally, a simulation is done for the examples of double - fault cases. The simulation results demonstrate the effectiveness of the proposed tolerant - fault control method.
