This paper presents an application of adaptive control techniques to the design of skid‐to‐turn (STT) missile autopilots. More specifically, a linear–quadratic robust adaptive controller is used to deal with the yaw channel control problem. The linear–quadratic control design is mainly motivated by its popular stability margins, while the robust parameter adaptation is expected to handle the missile model parameter uncertainties. The control design as well as the parameter estimation are derived in the discrete time domain using the delta operator formulation. The state variables as well as the stability margin are shown to demonstrate how the adaptive controller outperforms its underlying fixed parameter controller.
