Advanced Guidance Laws for Field-of-View and Impact Angle Constrained Engagements
This thesis deals with the development of guidance laws for interceptors with seeker field-of-view (FOV) and impact angle constraints. Two classes of guidance problems, namely, field-of- view and impact angle constrained ... -
Analysis of Proportional Navigation Class of Guidance Law against Agile Targets
(2017-12-12)Guidance is defined as the determination of a strategy for following a nominal path in the presence of o-nominal conditions, disturbances and uncertainties, and the strategy employed is called a guidance law. Variants of ... -
Beamforming and Target Tracking Methods for Active RF Phased Array Seekers
The end game guidance and control of an interceptor for neutralization of a hypersonic vehicle or a maneuvering aerial target is a challenging problem. This problem can be addressed in two ways: through faster autopilot ... -
Collision Avoidance And Coalition Formation Of Multiple Unmanned Aerial Vechicles In High Density Traffic Environments
(2014-08-07)This thesis addresses the problems of collision avoidance and coalition formation of multiple UAVs in high density traffic environments, proposes simple and efficient algorithms as solutions, and discusses their applications ... -
Control and Safety of Multi-UAV Systems for Collaborative Payload Transportation and Target Tracking
Unmanned aerial vehicles (UAVs) have been widely used in reconnaissance, remote sensing, disaster relief, and agricultural applications. Many applications require multiple UAVs to cooperate to complete the assigned tasks. ... -
Cyclic Pursuit : Variants and Applications
(2018-02-11)The classical n-bugs problem has attracted considerable attention from researchers. This problem stems from the study of movement of a group of animals. In the context of multi- agent systems the problem has been modelled ... -
Design, Control and Experimental Validation of a Robust Adaptive Feedback Linearization Controller for a Quadcopter Manipulator System
A quadcopter manipulator system (QMS) is an aerial robot comprising a quadcopter with a three degree of freedom manipulator mounted at the bottom of the vehicle. An aerial robot can reach otherwise inaccessible ... -
Differential Evolution Based Interceptor Guidance Law
(2013-05-29)Kinematics based guidance laws like the proportional navigation (PN) and many other linear optimal guidance laws perform well in near-collision course conditions. These have been studied thoroughly in the literature from ... -
Distributed Computation With Communication Delays: Design And Analysis Of Load Distribution Strategies
(Indian Institute of Science, 2005-11-09)Load distribution problems in distributed computing networks have attracted much attention in the literature. A major objective in these studies is to distribute the processing load so as to minimize the time of processing ... -
From Particles to People: Vicsek-Inspired Behavioural Modelling Frameworks
In this thesis, we develop different modelling frameworks to capture the processes of opinion formation and disease spread. The common theme binding them is a nearest-neighbour-based interaction rule; while the closeness ... -
Glowworm Swarm Optimization : A Multimodal Function Optimization Paradigm With Applications To Multiple Signal Source Localization Tasks
(2009-05-05)Multimodal function optimization generally focuses on algorithms to find either a local optimum or the global optimum while avoiding local optima. However, there is another class of optimization problems which have the ... -
Guidance Laws For Impact Angle Constraints And Exo-Atmospheric Engagements
(2010-10-22)This thesis deals with development of guidance laws for advanced applications. Two class of guidance problems, namely, impact angle constrained guidance and pulsed guidance for exo-atmospheric engagements, are considered ... -
Impact Angle Constrained Guidance Using Cubic Splines
(2018-06-05)In this thesis the cubic spline guidance law and its variants are derived. A detailed analysis is carried out to find the initial conditions for successful interception. The results are applied to three dimensional ... -
An Integrated Estimation-Guidance Approach for Seeker-less Interceptors
(2018-07-16)In this thesis, the problem of intercepting highly manoeuvrable threats using seeker-less interceptors that operate in the command guidance mode, is addressed. These systems are more prone to estimation errors than standard ... -
Integrated Relative Position and Attitude Control of Distributed Spacecraft Formation For High Resolution Imaging
One of the major challenges in space technology is to achieve high resolution imaging of the intended area on demand to meet civilian and military applications. Spacecraft formation flying with coordinated control of smaller ... -
Longitudinal Acceleration-based Variable Speed Bio-inspired Guidance Law
Most analyses of existing interceptor guidance laws assume the interceptor speed to be constant, which simplifies mathematical analysis and enhances predictability in interception characteristics. In reality, this is not ... -
