Abstract:

This paper puts forward the technique of worst case analysis for flight control system under the influence of some important factors. The integrated processs of worst case analysis is given. The disturbance models of wind, thrust deviation, control parameters error and structure errors are established.Then the method of combining the direct substituting with orthogonal test for worst case analysis is presented, and the detailed algorithm process is represented.

Key words: worst case analysis, wind, thrust deviation, control parameters error, structure error, reliability simulation, flight control system
