Abstract In this study, we focused on robotic swarms, allowing multiple anonymous autonomous robots to gather and move mutually in tasks. We proposed a method design parameter of the control barrier function (CBF) swarm so that can achieve collision-free deformation considering environmental conditions. analyzed responses perturbations swarming robots, which applied CBF. Although guarantee safe...

A finite measurement time is at the origin of transient (sometimes called leakage) errors in nonparametric frequency response function (FRF) estimation. If FRF varies significantly over resolution experiment (= reciprocal time), then these transients (leakage) cause important bias and variance estimate. To decrease errors, several local modeling techniques have been proposed literature. This ar...

In this paper, a structural damage identification method (SDIM) is developed for plate-like structures. This method is derived using dynamic equation of undamaged/damaged plate, in which local change in flexural rigidity is characterized utilizing a damage distribution function. The SDIM requires to modal data in the intact state and frequency response of damage state where most of vibration ba...

In this paper, a new algorithm for system identification based on frequency response is presented. In this method, given a set of magnitudes and phases of the system transfer function in a set of discrete frequencies, a system of linear equations is derived which has a unique and exact solution for the coefficients of the transfer function provided that the data is noise-free and the degrees of...

Because of random nature of many dependent variables in coastal engineering, treatment of effective parameters is generally associated with uncertainty. Numerical models are often used for dynamic analysis of complex structures, including mechanical systems. Furthermore, deterministic models are not sufficient for exact anticipation of structure’s dynamic response, but probabilistic models...
