Adjustable range trajectory design with multiple constraints for precision guided vehicles

In order to accommodate different combat missions, modern vehicles should be capable of covering wide range and accurately striking a target with multi-constraints, such as the common aero vehicle (CAV) et al. This paper set up the adjustable range and precision guided trajectory models, and analyzed multiple processing constraints and terminal constraints in flight. Furthermore, to enhance control efficiency, this paper improved on an original formula and gained a new law of attack angle. On the basis of the above work, a complete flight scheme for accuracy guidance was designed regarding angle of attack as the control variable to seek the flight program of maximum range, minimum range or a certain fixed range. The simulation results indicated the feasibility and validity of the control scheme. The research aims to provide a new approach for the integral trajectory design.
