ANALYSIS ON GENERALIZED IMPACT ANGLE CONTROL GUIDANCE LAW

Guidance Law for Impact Time and Angle Control with Control Command Reshaping

In this article, a more generalized form of the impact time and angle control guidance law is proposed based on the linear quadratic optimal control methodology. For the purpose on controlling an additional constraint such as the impact time, we introduce an additional state variable that is defined to be the jerk (acceleration rate). Additionally, in order to provide an additional degree of fr...

Guidance Law for Impact Time Control

A nonlinear guidance law is presented for the im-pact time control of an interceptor against a stationary target. Exact closed form expressions for impact time and the guidance command are derived. For a given engagement geometry, a given impact time corresponds to a unique initial heading error. For interceptors launched with any other initial heading error, a term proportional to impact time ...

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...

Fuzzy Logic-based Terminal Guidance with Impact Angle Control

This paper presents a new formulation of terminal guidance law which controls the impact attitude angle while minimising the miss distance. The formulation is based on the fuzzy logiccontrol approach. Unlike many prevalent designs, the proposed guidance law does not require linearisation of missile-target engagement model. Numerical simulation results demonstrate that the proposed guidance law ...
