Time-to-go Polynomial Guidance Laws with Terminal Impact Angle/Acceleration Constraints
نویسندگان
چکیده
This paper deals with a generalized impact angle control guidance law with terminal acceleration constraint, which is called the Time-to-go Polynomial Guidance (TPG). The guidance command of TPG is initially assumed as a polynomial form of tgo, and then the coefficients of this polynomial function are designed to satisfy the terminal impact angle and zero miss-distance constraints. TPG presents a simple form, and it can easily achieve the terminal acceleration and its time-derivative constraints which are predetermined by the specified values. In this study, linear trajectory solutions of TPG are derived and analytically investigated. Numerical and adjoint simulations are performed to investigate the performance of TPG.

Time-to-go Polynomial Guidance with Impact Angle Constraint for Missiles of Time-Varying Velocity
In this paper, a Time-to-go Polynomial Guidance (TPG) law satisfying impact angle constraints for missiles of time-varying velocity against stationary target is investigated. The guidance law assumes the magnitude of guidance commands as a polynomial function of time-to-go with two unknown coefficients. The coefficients are determined to satisfy the two terminal constraints, which are the termi...
متن کاملGuidance 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...
متن کاملCapture Region Analysis for Missile Guidance with Field-of-view Constraint against Moving Target
A capture region for missile guidance laws under field-of-view constraint is analyzed. To make a missile intercept a non-maneuvering target, physical constraints including seeker`s field-of-view and acceleration limit should be considered, because these constraints may restrict maneuver of the interceptor. The characteristics of look-angle constraint guidance laws is studied, and feasible traje...
متن کاملA Three Stage Terminal Fuzzy Guidance Law for Reentry Vehicles
An advanced guidance law is developed for reentry phase of a reentry vehicle. It can achieve small miss distance and desired impact attitude angle, simultanceously. To meet this requirment a guidance law based on the fuzzy logic approach is developed. It is partitioned into three stages. This guidance law does not require linearization of missile engagement model. Line-of-sight and flight path ...

A near-optimal midcourse trajectory shaping guidance algorithm is proposed for both air and ballistic target engagement mission attributes for generic long range interceptor missile. This guidance methodology is based on the maximum final velocity as the objective function and maximum permissible flight altitude as the in-flight state constraint as well as the head-on orientation as the termina...
