摘要：

Fault diagnosis problems of the carrier rocket actuator are investigated based on the multiple-model method. Firstly, the model of the carrier rocket with the actuator failure is established. Different from the traditional models where only additive faults are considered, this paper considers the multiplicative faults. Then a set of multiple-model unknown input observers are designed to generate a certain residual value, where an adaptive method is applied to estimate the value of the unknown input. Based on the residual value and multiple-model, the faults are determined. Finally, a numerical example is given to demonstrate the effectiveness of the proposed methods.
