| Abstract |
Hardware-in-the-loop Simulation(HILS) is a tool used for testing and validating real controllers with a real-time virtual plant. However, the fidelity of the plant being modeled in HILS determines the reliability of the tested controller. In this paper, an induction motor drive is developed in HILS. Both Cauer and Foster thermal networks are employed for thermal and loss modeling of switching blocks as well as the induction machine. The developed model is used to test a variant of a sliding mode-based control structure. Sliding mode-based controllers are robust to internal perturbations and external disturbances. Integral super twisting sliding mode control(ISTSMC) is the finally employed controller that eliminates the chattering phenomenon associated with other sliding mode-based control strategies. The ISTSMC controller is interfaced with the HILS device by building the controller in a rapid-control prototyping(RCP) device. The HILS testing of ISTSMC indicated that this controller increases the robustness of the system without adding thermal stresses to it. |
