Robust inversion of non-linear dynamic systems
ثبت نشده
چکیده
Weight reduction is becoming increasingly important in products that undergo cyclic loading, such as cars, aeroplanes, wind turbines, etc. The novelty of these dramatic design changes will cause material fatigue to become one of the key design drivers in the development of cars, aeroplanes, wind turbines and require tools to accurately predict the life time of a construction. The life time can be estimated with numerical simulation with virtual prototypes or experimentally in laboratory tests with physical prototypes on durability test rigs. The numerical simulation makes use of mathematical (finite element, multi-body) models to predict the cyclic stresses in a construction due to external excitations.

Design of Nonlinear Robust Controller and Observer for Control of a Flexible Spacecraft
Two robust nonlinear controllers along with a nonlinear observer have been developed in this study to control a 1D nonlinear flexible spacecraft. The first controller is based on dynamic inversion, while the second one is composed of dynamic inversion and µ-synthesis controllers. The extension of dynamic inversion approach to flexible spacecraft is impeded by the non-minimum phase characteristi...

متن کاملDefinition of General Operator Space and The s-gap Metric for Measuring Robust Stability of Control Systems with Nonlinear Dynamics
In the recent decades, metrics have been introduced as mathematical tools to determine the robust stability of the closed loop control systems. However, the metrics drawback is their limited applications in the closed loop control systems with nonlinear dynamics. As a solution in the literature, applying the metric theories to the linearized models is suggested. In this paper, we show that usin...
