FPGA based speed control of PMBLDC motor using SVPWM technique in fuzzy controller

The main aim of this paper is to control the speed of PMBLDC motor by implementing SVPWM technique in FPGA based Fuzzy controller.BLDC motors are electronically commutated. An electronic controller replaces the brush/commutators assembly of the brushed DC motor, which continually switches the phase to the windings to keep the motor turning. The controller performs similar timed power distribution by using a solid-state circuit rather than the brush/commentators’ system. SVPWM techniques enjoy an assortment of advantages such as high output quality, less THD, low distortion and low rating of filter component. Also a current controlled technique for BLDC motor drives is used.Fuzzy logic controller enjoys the advantage of having low settling time ascompared to traditional controller and is simpler than latest complexcontrollers and speed control of PMBLDC motor is effective.The Spartan-3E family of Field-Programmable Gate Arrays (FPGAs) is specifically designed to meet the needs of high volume, cost-sensitive consumer electronic applications. The Spartan-3E family builds on the success of the earlier Spartan-3 family by increasing the amount of logic per I/O significantly reducing the cost per logic cell. New features improve system performance and reduce the cost of configuration.
