Combined Proportional Navigation Law for Intercepting High-speed Maneuvering Targets Based on MPSP

Abstract

Aiming at the interception problem of high-speed maneuvering targets, a combined proportional navigation law based on model predictive static programming (MPSP) is proposed. Firstly, according to the interception terminal relationship for high-speed non-maneuvering targets, the variable coefficient proportional guidance law is obtained. The guidance law is then used to generate a set of predictive control sequences for high speed maneuvering targets. The motion and control models for intercepting high-speed maneuvering targets are then discretized to obtain analytical suboptimal control laws. Finally, the MPSP method is used to modify the prediction control sequence multiple times to obtain a near optimal control sequence. The simulation results show that the guidance law is superior to the proportional guidance law, negative proportional guidance law and variable proportional guidance law in the interception parameters such as the acquisition range, trajectory characteristics and overload variation.
