Despite the need of a complex motor controller, the simple construction of BLDC motors offers several inherent advantages not provided with brushed DC motors in terms of low inertia, high torque and a very wide speed range. The BLDC motors include, Longer service life due to a lack of electrical and friction losses and also free maintenance due to a lack of brushes and mechanical commutators. The EMI and noise are reduced because of the elimination of ionizing spikes from brushes. The control system of BLDCM is highly complex drive due to nonlinear nature. In such a system for implementing control algorithm needs high speed processor. In this work the controller Xilinx Spartan-6 FPGA is a demonstration platform intended to become familiar with the new features and availability of the Spartan-6 FPGA. The various experimental tests are carried out in 3Ф BLDCM .The experimental results are reported in order to verify the steady state, transient and robustness performance of the controller.

Cascade Speed Regulation System has the nonlinear characteristics and whose structure parameters are variable easily. Fuzzy control theory which based on conventional Cascade Speed Regulation System is introduced into such system. An asynchronous motor model is built, and a fuzzy parameter self-tuning controller is designed in this paper, the controller is simulated in Matlab, The simulation result shows the difference between the conventional PI controller and the fuzzy parameter self-tuning PI controller. From these simulation results, all performance indexes of the fuzzy PI controller with parameters self-tuning are vastly superior to those of the conventional PI controller.

This paper proposes a modeling and controller design approach for a wind-diesel hybrid system including dump load. The proposed control scheme for power quality is fuzzy PI controller which has advantages of PI and fuzzy controller. Simulation results show that the proposed controller is more effective against disturbances caused by wind speed and load variation than the PI controller, and thus it contributes to a better quality wind-diesel hybrid power system.
