Design of AIM Model Reference Variable Structure Flight Control System

The variable structure autopilot of some middle-ranged air intercept missile (AIM) is designed according to model reference variable structure terminal sliding mode control scheme. It is demonstrated by theoretical analysis,that the scheme efficiently improves the dynamic characteristics and is robust to the system uncertainties. Digital simulation results show that the designed variable structure autopilot possesses satisfactory instruction following performance and is non sensitive to system parameter variation.
