Attitudes play a significant role in determining how individuals process information and behave. In this paper we have developed a new computational model of population wide attitude change that captures the social level: how individuals interact and communicate information, and the cognitive level: how attitudes and concept interact with each other. The model captures the cognitive aspect by r...

This series of two papers (Parts 1 and 2) provides a rigorous comprehensive approach to the design of the principal software algorithmsutilized in modern-day strapdown inertial navigation systems: integration of angular rate into attitude, acceleration transformation/integration into velocity, and integration of velocity into position. The algorithmsare structured utilizing the two-speed updati...

Abstract: This paper presents the development and implementation of a single tilting rotor multirotor helicopter. A single tilting rotor multirotor helicopter is proposed that allows for decoupled lateral acceleration and attitude states. A dynamics model of the proposed multirotor helicopter is established to enable control system development. A control system architecture and daisy chaining-b...

Space manipulators mounted on an on-o thrustercontrolled base are envisioned to assist in the assembly and maintenance of space structures. When handling large payloads, manipulator joint and link exibility become important, for they can result in payload-attitude controller fuel-replenishing dynamic interactions. In this paper, the dynamics model of an Nexible-joint space manipulator is develo...

This paper presents the design, analysis, and performance evaluation of an attitude filter for an Intervention-Autonomous Underwater Vehicle (I-AUV) working in tandem with an Autonomous Surface Craft (ASC). In the proposed framework, an ASC aids an I-AUV to determine its attitude by providing an inertial reference direction vector through acoustic modem communications, which is measured in body...

A higher-order perturbation theory for the rotation of a uniaxial satellite under gravity-gradient torque demonstrates that known special configurations of the attitude dynamics at which the satellite rotates, on average, as in a torque-free state, are only the result of an early truncation of the secular frequencies of motion. In addition to providing a deeper insight into the dynamics, the hi...

We present a model of opinion and attitude dynamics that incorporates multi-dimensionality of a single attitude, i.e. attitudes are composed of evaluations of several features. We include selective exposure that is modeled as a hierarchical version of the bounded confidence model. Individuals adapt their feature evaluations if their attitudes and the respective feature evaluation are sufficient...

A modified method for satellite attitude control system in presence of novel actuators is proposed in this paper. The attitude control system is composed of three fluidic momentum controller (FMC) actuators that are used to control Euler angles and their dynamics is considered in satellite attitude equations as well. L1 adaptive control is utilized for satellite three-axial ...

The assumption that individual behavior has an antecedent evaluative foundation is an important component of theories in sociology, psychology, political science, and economics. In its simplest form, the antecedent evaluation is a positive or negative attitude toward an object that may affect an individual’s object-related behavior. This attitude may be influenced by the attitudes of other pers...

An efficient and accurate computational approach is proposed for a nonconvex optimal attitude control for a rigid body. The problem is formulated directly as a discrete time optimization problem using a Lie group variational integrator. Discrete time necessary conditions for optimality are derived, and an efficient computational approach is proposed to solve the resulting two-point boundary-val...
