Adaptive Fast Fixed-Time Three-Dimensional Guidance Law With Acceleration Saturation Constraints

Blog Article

This paper investigates continuous anti-saturation three-dimensional guidance law against maneuvering target at the desired line-of-sight (LOS) angles.Firstly, in the light of fixed-time stability, fast nonsingular terminal sliding mode is designed without the limitation of odd-ratio fractional order.Then, with the limits of lateral acceleration midi-dresses saturation, continuous guidance law is proposed to guarantee that desired LOS angles are reached and maintained after the specified time, while adaptive law is implemented to estimate the information on maneuver accelerations of the attacking missile.Finally, Flower Shadow Box numerical simulations are presented to validate the effectiveness and rationality of the designed scheme.
