Localization in wireless sensor networks is an important functionality that is required for tracking personnel and assets in industrial environments, especially for emergency response. Current commercial localization systems such as GPS suffer from the limitations of either high cost or low availability in many situations (e.g., indoor environments ...

Collocated Versus Non-collocated Control
1997In the foregoing chapters, we have seen that the use of collocated actuator and sensor pairs, for a lightly damped flexible structure, always leads to alternating poles and zeros near the imaginary axis, Fig.6.1.a. In this chapter, using the root locus technique, we show that this property guarantees the asymptotic stability of a wide class of single ...

Superconvergent gradient smoothing meshfree collocation method
Computer Methods in Applied Mechanics and Engineering, 2018A superconvergent meshfree collocation method with smoothed nodal gradients is presented. In this method, the first order smoothed gradients of meshfree shape function are constructed through a meshfree interpolation of the standard derivatives of ...

Collocated and non-collocated control
2017This chapter presents closed-loop collocated and non-collocated control approaches for flexible manipulator systems. A closed-loop control strategy using hub angle and hub velocity feedback for rigid-body motion control and end-point acceleration feedback for flexural motion control is considered.

An adaptive isogeometric analysis collocation method with a recovery-based error estimator
Computer Methods in Applied Mechanics and Engineering, 2019In this paper, we propose an enhanced isogeometric analysis (IGA) collocation method. It is well known that the location of the collocation points plays an important role in the accuracy and stability of IGA collocation methods. This is particularly true

Structural Safety, 2018
Polynomial chaos expansion (PCE) is widely used to build a surrogate meta-model of the performance function for structural reliability analysis. The number of terms to be determined in PCE grows exponentially with the number of input random variables ...
