Microwave phase shifter in phased-array radar, communications, instrumentation, heavy ion accelerator and the missile attitude control system has a broad application prospects.

As a synthesis method in control system, the sliding mode of variable structure control is invariable, and which is its most excellent advantage in the missile attitude control system.

This paper investigates the large Angle attitude post stall maneuver control for the agile turn phase of an air-to-air missile that has high off-boresight capability and head reverse maneuverability.
