| Abstract: | Aerospace industry is a high?risk industry, an unsuccessful launch test may cause great loss of millions, even catastrophe. Therefore, fault diagnosis technique is very important and valuable in aerospace engineering. In this paper, detection approaches of pulse fulse faults and step faults in terms of dynamical system of launch vehicle are established respectively by using analytic redundancy method, estimation algorithm of faults amplitude is presented as well. |
