Description
Summary:•The paper presents a sliding mode controller for a wound rotor synchronous generator.•The machine stator voltage amplitude is regulated.•The control algorithm, that does not requires the knowledge of the parameters.•The controller is implemented and validated experimentally. In this paper, a sliding mode controller for the stator voltage amplitude of a stand-alone wound rotor synchronous generator is presented. The standard dq-model of the electrical machine connected to an isolated inductive load is obtained. Then, the control law is designed using sliding mode techniques. The controller introduces a dynamic extension so that the stator voltage amplitude has relative degree one. As a result, a fast controller, robust to both machine and load parameters variations, is obtained. The control algorithm, that does not requires the knowledge of the parameters, is implemented and validated experimentally.
