Abstract

The Induction Motor is the most widespread motor for industrial use, thanks to its simple construction, low cost and robustness, both at constant and variable-speed applications. Continuous Control Set Model Predictive Current Control strategy has not been deeply investigated for Induction Motor, due to its complicated state model. In fact, it can be described by a second order model, which requires both stator and rotor electric parameters. In this work, the Continuous Control Set solution is implemented. The internal motor model exploited by the current control is derived. Moreover, an Integral Action is included directly in the Model Predictive Control formulation, avoiding steady-state bias errors caused by parameter uncertainty. The proposed formulation is deeply described and compared to the standard one. Many experiments are designed to validate the control scheme. In details, comparisons with benchmark PI controller are proposed and discussed, highlighting advantages and drawbacks of the two solutions.
