State feedback control with time delay
… and active schemes. We introduce the problem of state feedback control and provide the classical solution in the form of Ackermann formula. We then identify the limitations of the classical approach and present the more elegant solution of partial pole assignment without spillover. We highlight …

State Feedback Design Methods: Eigenstructure Assignment and LQR Cost Functional Synthesis
… involves two distinct but related topics in state feedback design methodology: (i) the assignment of a system's closed-loop eigenvectors and eigenvalues ("eigenstructure"), and (ii) the synthesis of Linear Quadratic Regulator (LQR) cost functional weighting matrices.

State Feedback Control of a Single-Loop Thermosyphon System Via a Quotient Controller
The objective of this work is to design a quotient controller to stabilize a chaotic flow in a single loop thermosyphon system with a high heat index. The thermosyphon loop is heated from below and cooled from above, which causes time-dependent chaotic flow when the external heat index is above a …
