Fractional calculus guidance algorithm for aircraft pursuit-evasion

Aiming at intercepting hypersonic target in a pursuit-evasion game, this paper presents a fractional calculus guidance algorithm based on a Nonlinear Proportional and Differential Guidance law (NPDG). According to relative motions between the interceptor and target, quantitative values were proposed for the parameters of the fractional calculus guidance law and system stability condition was given. Numerical experiment results demonstrated that the proposed guidance algorithm effectively reduced the miss distance against target maneuver. A stronger robustness compared to the NPDG was also shown under noisy condition.
