Linearized impulsive guidance laws.

AIAA Journal, 1965
We now summarize our results. Whenever /5 is within some e neighborhood of 90° (e -> 0), a and y are obtained from Eqs. (6a) and (6b) or Eqs. (9), and ft is obtained from Eq. (2b) or Eq. (8), where in the latter equation the ± signs must be distinguished according to whether ft has been increasing or decreasing in its passage through 90°.

Optimal Proportional-Integral Guidance Law

2020
This chapter proposes a new optimal guidance law based on PI concept to reduce the sensitivity to unknown target maneuvers. By augmenting the integral ZEM as a new system state, a linear quadratic optimization problem is formulated and then the proposed guidance law is analytically derived through optimal control theory. The closed-form solution of the

A VSS guidance law for agile missiles

Guidance, Navigation, and Control Conference, 1997
A guidance law based on application of sliding mode control is proposed in the present paper. The structure of the guidance extends the current literature by adding a range term in the sliding manifold equation. Under the hypothesis of off-boresight capability, the sliding mode structure provides a guidance law with potential for maneuvering and ...

Guidance Laws for Short-Range Tactical Missiles

Journal of Guidance and Control, 1979
Introduction G laws for short-range tactical missiles have become a well-researched topic over the past 35 years with publications of analytical treatment and implementation of missile guidance going back to the 1940's. Thus, much of the guidance development available in the literature predates that which is known as modern control theory.

Implementing Air Combat Guidance Laws

Journal of Dynamic Systems, Measurement, and Control, 1989
The one-on-one air combat problem has been studied by both theoreticians and pilots, beginning with the “dogfights” of World War I. Since that time, aircraft and weapon capabilities have vastly increased, but no comparable improvements in pilot tactics or maneuver algorithms have been acknowledged.

An All-Aspect Near-Optimal Guidance Law

Dynamics and Control, 2000
In this paper, a new guidancelaw known as the all-aspect proportional navigation (AAPN) guidancelaw is formulated. AAPN is a modification of traditional proportionalnavigation, with an additional term added to improve performanceat large heading error angles.

3D Unified Approach to Missile Guidance Laws

The Fourth International Conference on Control and Automation 2003 ICCA Final Program and Book of Abstracts ICCA-03, 2003
Since the proportional navigation guidance law was first introduced, many of the researchers had proposed different methodologies to investigate the corresponding performances of all the existing guidance laws. In 1997, Yang and Yang introduced an unified approach, in that paper the authors found that under the proposed framework, all the existing ...

Min-Max Guidance Law Integration

2007
This chapter deals with air-to-air missile guidance law design. We model the terminal engagement of a ramjet missile with radar seeker lock on a single target (generic aircraft). We consider a realistic interception simulation with measurement errors and, more particularly, radome aberration errors.We define an extended Kalman filter to compensate in ...
