Design and test of electric drives with “model-free” predictive control
For applying the Model-based Predictive Control, a very deep knowledge of the drive behaviour is required, in order to develop a model suited to reproduce the dynamics of the drive under the applied voltage excitation and operating conditions. To overcome this drawback, an effective solution, referred to as Model-free Predictive Control (M-fPC)has been recently proposed. According to this approach (as an example, applied to a current control), the current variations relative to a given voltage vector are stored in a Lookup Table. The current prediction is later obtained by accessing the LUT in the position related to the considered voltage vector. The proposed project is aimed to highlight merits and drawbacks of the M-fPC and to develop new solutions to apply it to electric drives.
