State Variable Analysis and Design topics include: Concepts of state, state variables and state model, solutions of state equations, controllability and observability, pole placement by state feedback, observer systems and state models for linear continuous-time systems. State-variable analysis, also known as state-space analysis, is a procedure that can be used to analyze and design systems. It can be applied to linear and nonlinear circuits, as well as circuits with time-varying parameters.  A state variable is a characteristic of a system that can be described by a set of first-order...
