<P>The key to a successful application of control theory is modeling. Chapter 2 describes how to model individual components using difference equations, and Chapter 3 details how to analyze these ...

For example, Simulink allows you to build and test a feedback control system using block diagrams, while LTspice allows you to simulate the switching behavior and losses of the converter.

A linearized model of an HVDC system is presented in a control block diagram form. The converter models (rectifier and inverter), DC transmission system, phase lock oscillators (PLOs) and the HVDC ...
