Design of Fuzzy-Pid with Landsman Converter (LC) Fed BLDC Drive Using IFOC Controller

Abstract

In this paper, fuzzy - PID control is designed to improve the settling time of DC link voltage of the Photovoltaic (PV) array fed landsman converter (LC). In all platforms such as medicals, automobile the utilization of variable speed drives is increased and which are directs to brushless DC motor demand in increasingly. Indirect Field Oriented Control is used to make precise and robust speed control with ripple minimization of torque. Back-EMF estimation method is contributing with IFOC control for obtaining accuracy speed in sensor-less approach and control the dynamic changes in speed. Dc link voltage of LC is maintained at constant using the Fuzzy-PID control which maintains the BLDC steady state condition while the motor speed at dynamic load as well as set point variation. The performance of IFOC based brushless DC motor is improved with high efficiency and in the MATLAB/Simulink platform the proposed system results are verified.
