This paper presents a sliding mode controller for a wound rotor synchronous machine, acting as a generator for an isolated load. The standard dq-model of the machine is connected to a resistive load. A sliding surface is defined in order to fulfill control objectives, and the Ideal Sliding Dynamics is proved to be stable. From the desired surface, the standard sliding methodology is applied, and a...
In this brief two sliding mode control alternatives to regulate the stator voltage amplitude for a stand alone wound rotor synchronous generator are presented. Both controllers use the stator voltage -component error in the sliding surface. In a first case an outer proportional-integral (PI) loop controller is added to provide the proper d-voltage component reference. The second approach consists...
In this paper the properties exhibited by the IDA Passivity-based Controller (PBC) design methodology for developing Output-Feedback Controllers (OFC) are illustrated by means of the particular system composed by a synchronous generator connected to an infinite bus via a Thyristor Controlled Series Capacitors (TCSC). Two OFC are presented, one that does not involve the unmeasurable state and other...
This paper presents an energy-based model of a series hybrid electric vehicle. The proposed propulsion system has a new configuration using a wound-rotor synchronous generator (WRSM) and a doubly-fed induction machine (DFIM). From the classic dq dynamical equations of the WRSM and DFIM the port-controlled Hamiltonian models of each machine is described. One of the abilities of the port-based models...
