Shipboard power systems that service large-scale dynamic loads and electric propulsion can significantly improve their performance by adding controllable energy storage. These systems require power management controls that consider dynamics like gene

The dynamics of a general class of weakly nonlinear oscillators can be used to control power converters to create a self-forming AC network of distributed generators. Many control stability results for these “virtual” oscillators consider the int

This paper solves the inverse dynamics of a tethered kite analytically. Specifically, the paper presents a procedure for determining the angle of attack, induced roll angle, and tether tension magnitude needed to achieve a desired combination of tran

In the design of nuclear reactor systems, reliability is always a top consideration. Their main control method is the movement of “control rods” which inhibit the rate of reaction. Various gravity-based fail-safe methods are available during the

A semi-active hybrid energy storage system, consisting of a Li-ion battery pack, dc/dc converter, and Li-ion capacitor pack was developed for a range extended plug-in vehicle. The vehicle has a series-parallel drivetrain with two electric motors, a g

Many mobile platforms and small power systems utilize a set of loads, which consume some resource, to accomplish a task. If there are inadequate resources available to accomplish the system's task, load requests must be modified in some way. This pap

Small power systems are often used in support of broader systems like factories, climate control, and electric warships. Aggressive operation of the power systems often creates power shortfalls, which can be studied and controlled by assigning a valu
