IDENTIFICATION OF LOCAL NONLINEARITIES IN DYNAMIC SYSTEM VIA STOCHASTIC OPTIMAL CONTROL APPROACH

In the analysis of dynamic characteristics of space structures, the connecting elementsplay an important role in the overall dynamics of the structure, which often lead to the structureexhibits local nonlinearities. Generally speaking, the main part of the structure can be regardedas linear with sufficient accuracy, but it is often difficult to model these local nonlinear elementsbecause the complexity of their configuration and operating mode. Therefore, an increasing amountof attention has recently been d...
