Fuzzy side force control for missile against hypersonic target

An integrated fuzzy-logic-based missile side force control mechanism is proposed for the interception of ballistic targets in three-dimensional space. Stringent scenarios when the missile intercepts the ballistic target at higher attitudes are considered. Conventional guidance systems with the aerodynamically controlled mechanism alone are usually incapable of engaging a high-speed target at low-air-density layers. To overcome the difficulty because of insufficient manoeuvrability, a fuzzy side force control scheme configured with two additional auxiliary thrusters is proposed to generate extra transverse acceleration and thereby to reinforce the engagement performance. A simulation study proves the effectiveness of the proposed approach.
