The paper develops a performance analysis model of flight control systems subject to the electromagnetic environment driven by switched linear systems. In this paper, hidden Markov model (HMM) is employed to describe the characteristics of digital electromagnetic interferences. The model characterizes the interior relationship between field strength and other factors of electromagnetic interferences. At the same time, it is proved that the model has higher accuracy compared with other commonly used modeling methods. This paper also proposes a fast initial value selection strategy in order to overcome the problem of the sensitivity to initial value selection existing in traditional parameter estimation algorithm of HMM. And this strategy proposed in this paper can accelerate the process of model update. Finally, this model is used to analyze the performance of the switched flight control system using the signal generated by HMM.
