An optimal strategy based on minimum effort control and also with terminal positionconstraint is developed for an exoatmospheric interceptor with a fixed- interval guidance time. It isthen integrated with sliding-mode control theory to drive an optimal sliding-mode guidance law forfixed-interval guidance time. In addition, this guidance law is generalized for intercepting anarbitrarily time-var...

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 ...

background: parenting style in communication with teenagers is a complex and double way process that affects progress and success of all generations both at present time and future. due to the importance of having accurate knowledge about mothers' parenting style and its underlying factors, it has been assessed in this study. methods: this study was a descriptive cross-sectional study on 737 fe...

introduction: consultation and guidance is a process of learning which is done through the relationship between two individuals. in this mutual relationship, the counselor, through his scientific and occupational skills and qualification, tries to help the students using the methods corresponding to their needs. the main objective of this study was to provide a framework for the management of t...

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...
