Missile Guidance Laws Based on SMC and FTC Techniques

Proportional navigation (PN) has attracted a amount of interest in the missile interception and design of guidance laws due to the high effectiveness and simple implementation [299, 332, 221, 7]. Specially, PN guidance laws can be easily applied to many-to-one engagement scenarios and achieve the cooperative simultaneous attack of multiple missiles against their common target [123]. However, the PN guidance law is more applicable for the task of intercepting a non-maneuvering target or a weakly maneuvering target. In practice, target acceleration can change rapidly. For intercepting a target with powerful maneuvering capability, the performance of PN is degraded and it may be ineffective for some orientations between missile and target.
