Novel Adaptive Control Strategies for Permanent Magnet Synchronous Generator Based Wind Power Generation

Abstract

AbstractIn the variable-speed wind turbine generators, the rotor speed and position sensors are usually used to control, monitor, and protect the system smoothly operate through measuring the values of the rotor speed and position. Nevertheless, these sensors are very sensitive to temperature and environmental changes. To find more reliable solutions for the wind turbine generators’ stable operation, this paper presents two sensorless control strategies for permanent magnet synchronous generator (surface-mounted) based wind power generation. In the first strategy, the adaptive sliding mode control method and deadbeat-based predictive current controller are applied. And in the second strategy, the deadbeat predictive controller is utilised in a model reference adaptive controller system. Among the methodologies which are used in these two control strategies, model predictive control and sliding mode control have been widely implemented to resolve complex control applications. To test two control strategies’ performance, two simulation models had been tested through MATLAB/SIMULINK environment and the relevant experiments.KeywordsAdaptive controlDeadbeat-based predictive current controllerModel predictive controlModel reference adaptive controlSliding mode controlSurface-mounted permanent magnet synchronous generatorWind power generation
