Reduced ordered modelling of time delay systems using Galerkin approximations and eigenvalue decomposition

S Chakraborty, SS Kandala… - International Journal of …, 2019 - Springer
In this paper, an r-dimensional reduced-order model (ROM) for infinite-dimensional delay
differential equations (DDEs) is developed. The eigenvalues of the ROM match the r …
