The guidance law is required for the aircraft to autopilot along the fixed path. The LOS(Line-of-Sight) guidance law is mainly used to follow the path. In this paper, we propose aircraft guidance systems that consist of LOS guidance law and the fuzzy self-tuning PID controller to follow the path more precisely. In addition, we compared the path following performance and feasibility of various e...

For a homing interceptor, suitable initial condition must be achieved by mid course guidance scheme for its maximum effectiveness. To achieve desired end goal of any mid course guidance scheme, two point boundary value problem must be solved online with all realistic constrain. A Newly developed computationally efficient technique named as MPSP (Model Predictive Static Programming) is utilized ...

In this paper we develop a methodology based on ballistics to estimate the landing footprint associated with the powered terminal descent phase of a Mars soft landing. The analysis is based on an idealized two-impulse thrust maneuver and leads to an analytical expression for the elliptical boundary of the landing footprint. Our goal was to develop a method (with low computational overhead) to e...

A guidance law, based on supervisory recurrent fuzzy neural network control (SRFNNC), is proposed for the autonomous underwater vehicle (AUV) guidance systems. This SRFNNC system is comprised of a recurrent fuzzy neural network (RFNN) controller and a supervisory controller. The RFNN controller is used to mimic an ideal controller and the supervisory controller is designed to compensate for the...

in this paper, the propagation of the waves in the laminated composite plates which is subjected to low velocity impact is investigated using the finite element method. a rigid metallic projectile with spherical nose is considered and the impact of this projectile with laminated composite is studied in this study. considering a finite element model the governing equations of the problem is disc...

Differential Game Based Guidance Law for High Angle of Attack Missiles By P. K. Menon and G.B. Chatterji Optimal Synthesis 450 San Antonio Road, Suite 53 Palo Alto, CA 94303 Abstract A nonlinear differential game theoretic intercept guidance law for short range missiles is derived.
