Abstract

This paper introduces an evolutionary programming algorithm to find near-optimal or feasible trajectory in a feedback form for an aircraft in an air combat with an air-to-air missile. The evader is modeled in a six degreeof-freedom model and the pursuer is modeled as a point mass. The evader’s aerodynamic and stability data are derived from wind tunnel and are presented in tabular forms. The missile uses proportional navigation guidance system to direct itself towards the evader and it has a boost sustain propulsion system which limit its inflight duration. In the proposed scheme, the optimal controls of the aircraft over a short planning horizon are solved online by Evolutionary Programming at each decision instant. Thereafter, the state of the system is updated by using only the feasible solution found by EP, and the process is repeated. The performance measure defining the objective of the aircraft is based on the time of capture or capturability. The evaluation of the candidate solutions are performed in parallel using master-slave configuration. The parallel performance is studied. Example of results are presented. Feasible trajectories were found in a relatively short period of time.
