    Real-time simulation of power electronic systems for electric ships is an essential technique for testing hardware and software in the loop. An important parameter of these simulations is the frame-time necessary to capture the dynamics of the system being simulated. Modern power electronic systems, using higher frequency pulse-width modulation (PWM) converter control, demand frame times that are ... View full abstract»

    Power systems involve continuous and discrete components and controls. The modeling of 'hybrid' power systems using a logical specification to define the transition dynamics of the discrete subsystem is described. A computational tool for reduction of the logical specification to a set of inequalities is discussed. The use of the transformed model in a dynamic programming approach to the design of...

    The objective of reconfiguration is to re-route power during failure or compromised conditions to improve fight through capability and survivability. Rapid algorithms for the task may serve the dual purpose of managing power flow under dynamic load change. Among the critical constraints of power redirection is the line current rating. Reconfiguration algorithms serve an equally useful task in syst... View full abstract»

    The electric power systems in U.S. Navy ships supply energy to sophisticated systems for weapons, communications, navigation and operation. During battle, various weapons may attack a ship causing severe damage to the electrical system on the ship. This damage can lead to de-energization of critical loads which can eventually decrease a ship's survivability. It is very important, therefore, to mai... View full abstract»

    We present a systematic design method for automatically controlling the reconfiguration of shipboard power systems, which is implemented primarily via switching actions. This method takes advantage of the hybrid system model of the power network, in which certain parameters may be varied discretely or continuously to control the system. Any given state of the discrete switches (relays) that are us... View full abstract»
