State space representation of electrical system

State Space Differential Equations 1. Draw circuit schematic and label components (e.g., R 1, R 2, C 1, L 1…) 2. Assign voltage at each node (e.g., e 1, e 2) 3. Assign current in each component (e.g., i 1, i 2, ..) and show positive current direction with arrows 4. Write equation for current for each component (e.g., i R1 = (e 1-e 2)/R 1 or i C1 = CDe 1) 5. A model is a mathematical representation of a physical, biological or in-formation system. Models allow us to reason about a system and make predictions about who a system will behave. In this text, we will mainly be interested in models describing the input/output behavior of systems and often in so-called \state space" form.
Sep 20, 2015 · Harish Ravichandar, a PhD student at UConn, shows two examples of using the state space representation to model circuit systems. Still don't get it? Have questions relating to this topic or others ... • The state of a system is a set of variables such that the knowledge of these variables and the input functions will, with the equations describing the dynamics, provide the future state and output of the system. • For a dynamic system, the state of a system is described in terms of a set of state variables. System u 1(t) u 2(t) y 1(t) y 2(t) • The state of a system is a set of variables such that the knowledge of these variables and the input functions will, with the equations describing the dynamics, provide the future state and output of the system. • For a dynamic system, the state of a system is described in terms of a set of state variables.

Aug 31, 2017 · State Space Representation of a System. The control system analysis fails for multiple-input multiple-output (MIMO) systems and the systems initially not at rest by using transfer function approach. The use of state space approach for the analysis of control systems enables to overcome the shortcomings of the transfer function approach.
CONTROL SYSTEMS, ROBOTICS, AND AUTOMATION – Vol. III – Description and Analysis of Dynamic Systems in State Space - Boris Lohmann ©Encyclopedia of Life Support Systems (EOLSS) DESCRIPTION AND ANALYSIS OF DYNAMIC SYSTEMS IN STATE SPACE Boris Lohmann Institut für Automatisierungstechnik, Universität Bremen, Germany In a state-space system representation, we have a system of two equations: an equation for determining the state of the system, and another equation for determining the output of the system. We will use the variable y(t) as the output of the system, x(t) as the state of the system, and u(t) as the input of the system.
