BLDC motor control design in Matlab/Simulink

The article describes the simple way of BLDC motor control development in the Simulink environment. This way of development is also called Model Based Design approach, which is nowadays rapidly gaining popularity. MBD should be very effective method for development time reduction and finds usage especially during fast prototyping phase. The simple BLDC motor controller has been created and presented in this paper. Because the Simulink itself cannot control any outside system or process itself, a real special software and hardware has to be connected to the personal computer. Described control algorithm has been developed for dSPACE environment with appropriate power and interface electronics. The sinusoidal control algorithms for low power sensor BLDC motor has been used.
