Modeling and Control of a Balloon Borne Stabilized Platform
نویسندگان
چکیده
A balloon borne stabilized platform has been developed for a remotely operated altitude-azimuth pointing of a millimeter wave telescope system. A modeling and controller design of the azimuth point system of the platform ispresented. Simulation results show that the system is capable of continuous operation with pointing rms to better than 0.01 deg. Ground testing results show continuous operation with pointing rms to better than 0.02 deg; while results of the first flight from the National Scientific Balloon Facility (NSBF) at Palestine, Texas show pointing rms better than 0.02 deg.

Nonlinear Modeling and Optimal Output Control of Two Wheeled Balancing Transporter
In this paper an optimal controller is proposed for a self-balancing electrical vehicle called Segway PT. This vehicle has one platform and two wheels on the sides and the rider stands on the platform. A handlebar, as a navigator, is attached to the body of Segway, with which the rider controls the vehicle. Since Segway uses electrical energy produced by batteries, resource consumption manageme...
متن کاملAdaptive Control of a Spin-Stabilized Spacecraft Using two Reaction Wheels and a 1DoF Gimbaled-Thruster
In impulsive orbital maneuvers, a large disturbance torque is generated by the thrust vector misalignment from the center of mass (C.M). The purpose of this paper is to reject the mentioned disturbance and stabilize the spacecraft attitude, based on the combination of a one degree of freedom (1DoF) gimbaled-thruster, two reaction wheels (RWs) and spin-stabilization. In this paper, the disturban...

In this study, mass, stiffness and damping matrices of the Nosrat jacket; located in Persian Gulf; equipped with Semi Active Tuned Mass Damper (SATMD) system have been derived after modeling the structure in SACS software. Owing to huge number of the degrees of freedom in the model, computation of on-line control of SATMD was time consuming. For this purpose, the size of the model was reduced i...
متن کاملDevelopment of a strategic plan through SWOT analysis to control traffic-borne air pollutants using CALINE4 model
Traffic is one of the main sources of air pollution in metropolitan areas. With development of transportation system, inappropriate vehicle production, and the use of low-quality fuels, increased pollution in these areas is inevitable. The current study tries to determine PM2.5, PM10, NO2, and CO emission dispersion, caused by traffic, using CALINE4 software. Ac...
