Abstract

This study which complete 3d proportional navigation simulation is the base with the matlab / Simulink simulation software ，the purpose of simulation.is simulating missile flight control section in the space proportional navigation guidance law of the missile flight path control . This study use the matlab / Simulink simulation software as a tool and take proportional navigation law as an example taking some actual inflections into consideration, establish the missile trajectory simulation module .Simulate the missile trajectory successfully. This article has achieved the following functions.

(1) Established plane proportional navigation trajectory simulation module to achieve a plane proportional navigation trajectory simulation, and the ratio of proportional navigation guidance law coefficients and parameters such as initial launch angle trajectory of proportional navigation guidance made a brief analysis.

(2)Established the proportional navigation of space trajectory simulation module and achieve the simulation proportional navigation of space trajectory.

(3) After completing space guided trajectory simulation ,it add some kinds of random variables, error and other effects of the missile trajectory simulation on the design in order to make the simulation more actually. It takes missing distance as a standard to analysis and quantitative comparison of the various parameters, and has done a brief analysis elucidated.
