Stability Margin Clearance of Missile Autopilot Using μ Anylysis

A new method of stability margin clearance of missile autopilot is described. First, a model of linear fractional transformation form is established for missile has uncertain parameters; then, the system stability margin requirements are seen as a virtual uncertainty and introduced into the model; Finally, the model is analyzed, and the clearance results about the missile autopilot performance is obtained. The results show this is a more efficient and accurate clearance method than traditional ones.
