These days, computer-based simulation is considered as the quintessential approach to exploring new ideas in the different disciplines of science, engineering and technology. To perform simulations, a physical system needs to be modeled using mathematics; these models are often represented by linear time-invariant (LTI) continuous-time (CT) systems. Oftentimes these systems are subject to additional algebraic constraints, leading to first or second order differential-algebraic equations (DAEs) or descriptor systems. Such large-scale systems generally lead to massive memory requirements and enormous computational complexity thus restricting frequent simulations as required by many applications. To resolve these complexities, the higher-dimensional system may be approximated by a substantially lower-dimensional one through Model Order Reduction (MOR) techniques. This book discusses computational techniques for the MOR of large-scale sparse LTI CT systems. Although the book puts emphasis on the MOR of descriptor systems, it begins by showing and comparing the various MOR techniques for standard systems.
The book also discusses the low-rank alternating direction implecit (LR-ADI) iteration and the issues related to solving the Lyapunov equation of large-scale sparse LTI systems to compute the low-rank Gramian factors.
Note that the low-rank Gramian factors are important ingredients for implementing the Gramin based MOR.
This book can be a text book for the graduate (i.e. Masters and Ph.D.) students/researchers of varies disciplines of science and engineerings. While the basic contents of this book can be helpful to the advanced Bachelor level students in any discipline. It would be highly valuable reference to researchers working in both academics and industries.
