Zusammenfassung:This paper present Hybrid Proportional Integral (PI) controllers (with fuzzy controller) as Series Hybrid or Parallel Hybrid configuration, for speed control of Permanent Magnet Brushless DC Motor drive for application to intermitted duty loads. The proposed configurations have superior performance compared to conventional PI controller amidst nonlinearities and parametric variations, when used as a continuous controller for the drive. In Series Hybrid configuration fuzzy controller provides precompensated input to the PI controller to reduce oscillation and fast operation, whereas, Parallel Hybrid utilizes Fuzzy logic based on-line parameters tuning, increasing the robustness under severe unknown plant nonlinearities. The dynamic characteristics of BLDCM such as speed, Torque, Current and Back EMF are observed and analyzed through simulation under MATLAB Simulink environment.
