Tuning of PI Speed Controller in DTC-SVM of Five Phase IPMSM Based on Biogeography Based Optimization (BBO) Algorithm

Proportional-Integral (PI) controllers are used in many industrial applications, as they have a simple structure and a robust performance. For tuning the control parameters of a PI controller, different methods have been proposed such as evolutionary algorithms. In this paper, Biogeography Based Optimization (BBO) algorithm is used for tuning the control parameters of a PI speed controller of a five-phase interior permanent magnet synchronous motor drive system fed by a three to five –phase matrix converter. Combination of BBO algorithm with the new drive scheme resulted good speed and torque responses with small overshooting both in steady-state and transient behaviours
