This lecture covers the selection of good pole locations in state-space control systems, focusing on dominant second-order poles to achieve specific time-domain specifications. It discusses principles to minimize control effort, examples of designing state-feedback control laws, choosing target models, and placing non-dominant poles. The lecture also explores model matching using reverse Bessel polynomials and the response of Bessel filters. It concludes with a summary of different methods for pole selection, including optimal control with Linear Quadratic Regulator.
