On this basis, the active control for stress intensity by a shape memory composite was discussed.
In this study, the numerical model of a shape memory alloy hybrid composite SMAHC plate was constructed. Besides, when the control effect reaches the standard, engineers began to focus on finding more economical and optimized control method.
The prediction of on-orbit closed-loop dynamics is based on analysis and ground testing. Some other studies have illustrated different controllers for active vibration control purpose [ 16— 21]; however, these two mentioned algorithms have not been widely used in wind tunnel tests yet. The effects of ER layer thickness, constraining layer stiffness and thickness on natural frequencies and modal loss factors are also presented. The term flight control system may also be used to describe the complete active control system of a flight vehicle, covering all its functions, which must work in complete harmony.
2003-08-18 Assigned to GENERAL DYNAMICS ADVANCED INFORMATION SYSTEMS, INC. Simulation results confirmed their effectiveness for enhancing the measure … precision. Therefore, the minimum value of the sum of two integral terms is essentially the compromise of the control effect and the control effort in optimal sense.
A kind of stable self-adaptive fuzzy controller based on scaling universes of discourse is designed in this paper for the vibration control of a large flexible space truss driven by piezoelectric sensors and actuators PZTs. The controlled nonlinear vibration response of the sandwich plate is computed and compared with that of the uncontrolled structural system. In the technical literature, the term surrogate models is often used only to describe sampling-based reduced-order models. A Solids 25 2215—229 2006• This paper presents an analytical model which can be used to determine the correct control schemes of induced strain actuators on a cantilever beam vibrating over a range of frequencies.
Recommendations Research and development work focused on the improvement of aeroelastic and aeroservoelastic analyses, simulations, and tests is still pursued in the United States and worldwide; funded by government agencies and industry; and carried out by industry, university researchers, and government research laboratories.
The first neural network, the emulator, models the complex, nonlinear output of the plant with respect to certain controls and stimuli applied to the plant. Three different control strategies were examined. The governing equations are solved for any time history of the dimensionless yield stress of the fluid which in turn is determined from the imposed response of the damper.
Another example of such a sensor is a starwheel with an associated magnetic sensor, as used in the distributors of new automobiles.
The characteristics of the antenna were checked in experiments using water.
Polarimetric sensors embedded in composite laminates can detect the development of this damage and they have an advantage over other sensors in being able to sense damage over long gauge lengths potentially, many metres.
