A robust output-feedback guidance law for homing missiles using l1-norm optimization theory

The paper presents the first application of lscr₁ optimization theory to terminal guidance. The novel design approach accounts for a bounded disturbance representing the unknown evasive tactic of the target, a noise signal affecting the measurements, and a saturation limit on the actuators of the pursuer. The resulting lscr ₁ guidance law is a linear output-feedback controller. The performance of the guidance law is assessed using a pre-selected interception scenario of a ballistic missile. Robust homing performance is demonstrated
