A 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 ...
متن کاملDesign of a Fuzzified Terminal Guidance Law
A new fuzzified terminal guidance law is proposed which employs the versatile feature of the fuzzy logic system to shape a beneficial trajectory for target interception. In the proposed scheme, the guidance law is partitioned into three stages in accordance with the relative range between the interceptor and target. Estimated line-of-sight angle, line-of-sight angle rate, line-of-sight angular ...

متن کاملAdaptive Terminal Guidance for Hypervelocity Impact in Specified Direction
The problem of guiding a hypersonic gliding vehicle in the terminal phase to a target location is considered. In addition to the constraints on its final position coordinates, the vehicle must also impact the target from a specified direction with very high precision. The proposed 3-dimensional guidance laws take simple proportional forms. The analysis establishes that with appropriately select...
متن کاملFuzzy 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 ...
