A Modified Midcourse Guidance Law Based on Genelarized Collision Course

Lyapunov-Based Pursuit Guidance Law with Impact Angle Constraint

This paper presents Lyapunov-based pursuit guidance law against stationary targets. To design a nonlinear guidance law, Lyapunov candidate function is introduced to reduce the angle between the velocity vector of a missile and the distance vector between the missile and the target. Therefore, the proposed guidance laws have the characteristic of pursuit guidance. To attack a target from a prede...

Midcourse guidance law with neural networks

A dual neural network ‘adaptive critic approach’ is used in this study to generate midcourse guidance commands for a missile to reach a predicted impact point while maximizing its final velocity. The adaptive critic approach is based on approximate dynamic programming. The first network, called a ‘critic’, network, outputs the Lagrangian multipliers arising in an optimal control formulation whi...

Integrated fuzzy guidance law for high maneuvering targets based on proportional navigation guidance

An integrated fuzzy guidance (IFG) law for a surface to air homing missile is introduced. The introduced approach is a modification of the well-known proportional navigation guidance (PNG) law. The IFG law enables the missile to approach a high maneuvering target while trying to minimize control effort as well as miss-distance in a two-stage flight. In the first stage, while the missile is far ...

A Comprehensive Approach to Develop a Continuous Fuzzy Guidance Law for Maneuvering Targets

Based on the idea of Continuous Fuzzy Guidance Law (CFGL), a andldquo;three-phase fuzzy guidanceandrdquo; (TFG) law is proposed for the class of surface to air homing missiles. The current approach enables the guidance law to track a maneuvering target from the beginning of the launch phase up to the terminal one while itdynamically attempts to keep miss-distance, flight time and control effort...
