Many industrial applications require new control techniques in order to obtain fast response and to improve the dynamic performances. One of the techniques used, is the fuzzy logic control which is characterized by robustness and insensitivity to the parameters variation. In this paper, the technique is applied for the design of a drive system fed from indirect power electronics conversion. The adaptive fuzzy controller (AFC) is applied in all regulation loops, starting from speed regulation of permanent magnet synchronous machine (PMSM) until the minimization of harmonics introduced by the line converter, including the control of power factor and DC-link voltage. We study the robustness of the controller using simulation results for different operating modes and parameters variation.
