Abstract:   (390 Views)
Classical structure of Doubly Fed Induction Generators (DFIGs) is not completely adapted in high-speed regions due to their brushes and slip rings. So in the Cascaded DFIGs (CDFIGs), the rotor windings of a given DFIG are supplied by another wound rotor induction machine leading to a complete brushless structure. This paper presents and compares Sliding Mode Control (SMC) and Terminal Sliding Mode Control (TSMC) methods to control the output voltage of CDFIG. The SMC and TSMC methods are identified as strong controllers with large stability and robustness margins. In this paper, the SMC and TSMC methods are evaluated and compared to the conventional Voltage Oriented Control (VOC) in terms of output voltage change, prime over speed’s variation, and nonlinear load. Simulation and experimental results using a TMS320F28335 based prototype system show that the SMC and TSMC techniques are more robust against parameter variations and uncertainties, and TSMC offers improved dynamic response.

  • Up to now, most control methods used for CDFIGs are based on voltage oriented control, and the nonlinear control method is not proposed for them.
  • The effectiveness of the proposed method in different scenarios such as feeding unknown, nonlinear and harmonic distorted loads is verified. As well, the effect of variable wind or prime mover’s speed on the output voltage is compared with three control methods.
  • In order to present a clear comparison between the proposed method and some recent methods, we compare three methods with simulation and experimental tests: VOC, SMC, and TSMC.
  • The state-space equation of CDFIG has 6 states. Using SMC and TSMC control, we use only the output variables of CDFIG, which feeds an isolated load and the output voltage control with constant and step-changed references is verified.
