Non-Adaptive Speed and Position Estimation of Doubly-Fed Induction Generator in Grid-Connected Operations
Abstract
The nonadaptive speed and position estimation scheme for a doubly-fed induction generator (DFIG) is presented in this article. The observer structure is based on the extension of the mathematical model of DFIG to the introduced H vector. Based on the defined H vector, the nonadaptive position and speed estimation is proposed. The Lyapunov method is extended to the practical stability theorem to stabilize the structure. The classic stator field-oriented control to active and reactive power control is used in the sensorless control system. The performance of the proposed algorithm of the speed and position observer is validated by simulation and experimental results using the 2 kW generator. The comparison tests to the classical model reference adaptive system based observer are provided. Finally, the article contains a summary in which the non-adaptive speed estimation is discussed in context to the adaptive reconstruction of the rotor speed and position.
