In this work, a state dependent Riccati equation (SDRE) missile guidance is formulated and studied. With the aid of a line of sight (LOS) fixed coordinate, the order of the system equations describing the three dimensional missile guidance problem is reduced to three.

Optimal Guidance Law in the Plane
Journal of Guidance, Control, and Dynamics, 1984Using the exact nonlinear equations of motion in the plane, an optimal guidance law for a vehicle pursuing a maneuvering evader is derived. It is assumed that a complete knowledge of the evader's motion is available to the pursuer. Both the pursuer and the evader move with constant velocities. The guidance law minimizes a weighted linear combination of

General 3D guidance law modeling
1995 IEEE International Conference on Systems, Man and Cybernetics. Intelligent Systems for the 21st Century, 2002Manoeuvring objects guidance is based on guidance laws. The most popular guidance laws are the proportional navigation laws. By now, the most efficient law in term of ability to cause capture is the pure proportional navigation. A new guidance law, as efficient as the pure proportional navigation, is modeled in this paper.

Observability-Enhancement Optimal Guidance Law
2019 Workshop on Research, Education and Development of Unmanned Aerial Systems (RED UAS), 2019This paper proposes a new optimal guidance law to enhance target observability for passive guidance with bearing-only measurement. A performance index that considers terminal miss distance, control effort and target observability criterion in an integrated manner is proposed first.

In comparison to western pharmaceutical regulations, China’s pharmaceutical legislation started much later in history. Because of these cultural, social, and economic discrepancies, foreign pharmaceutical companies hoping to introduce their drugs to the Chinese market have met many challenges and difficulties.

A class of robust guidance laws for reentry guidance
1977 IEEE Conference on Decision and Control including the 16th Symposium on Adaptive Processes and A Special Symposium on Fuzzy Set Theory and Applications, 1977The use of a dynamical model for a reentry vehicle employing a trajectory variable as the independent variable of evolution yields a guidance law which is insensitive to some of the exogenous disturbances commonly encountered by the vehicle. When there are several candidate variables upon which to base the guidance law, it is difficult to compare the ...

The previous chapters described the individual’s civic responsibility, identified the major obstacles she faces, and surveyed conventional sources of guidance to aid her in grappling with public issues. A dozen of the law’s principal tools and traditions for sound decision making were explained, followed by the expectations placed on jurors for ...

Modified Receding Horizon Guidance Law
IFAC Proceedings Volumes, 1998Abstract In this paper, a modified receding horizon guidance law (MRHG) is proposed which can be a proper guidance law when the accurate time-to-go is available only for a short time before the final time. In the proposed MRHG, RHG is used before the accurate time-to-go is available and after that, OGL is used until the missile intercepts the target ...

Game optimal receding horizon guidance laws and its equivalence to receding horizon guidance laws
KSME International Journal, 2002In this paper, a game optimal receding horizon guidance law (GRHG) is proposed, which does not use information of the time-to-go and target maneuvers. It is shown that by adjusting design parameters appropriately, the proposed GRHG is identical to the existing receding horizon guidance law (RHG), which can intercept the target by keeping the relative ...

Based on multisensor information fusion theory and optimal control theory of structure stochastic jump system, a new guidance law is proposed for air-to-air missiles based on information fusion of active radar and infrared sensor, and its validity is testified by analysis on simulation by building digital model of missiles.
