To improve the estimation accuracy, a novel time delay (TDE) method based on closed-form offset compensation is proposed. Firstly, we use generalized cross-correlation with phase transform (GCC-PHAT) to obtain initial TDE. Secondly, signal model using normalized cross spectrum established, and noise subspace extracted by eigenvalue decomposition (EVD) of covariance matrix. Using orthogonal rela...

Real-time hybrid simulation represents a powerful technique capable of evaluating the structural dynamic performance by combining the physical simulation of a complex and rate-dependent portion of a structure with the numerical simulation of the remaining portion of the same structure. Initially, this paper shows how the stability of real-time hybrid simulation with time delay depends both on c...

The optimal damping control for nonlinear time-delay systems with persistent disturbances is considered. Based on successive approximation approach (SAA), the optimal damping control (ODC) law is achieved by solving a decoupled sequence of inhomogeneous linear two-point boundary value (TPBV) problems without time-delay and time-advance terms. The ODC law of the original problem consists of accu...
