System of control of brushless DC motors using CPLD

The developed system of control of brushless DC (BLDC) motors is realized on the complex programmable logic device (CPLD). Using CPLD reduces the power consumption required for calculation the control vector and also the cost of the system. As opposed to the modern systems of control of BLDC motors, the given system uses only two Hall’s sensors. The control circuit is based on the operators of the logical signal convolution that significantly reduces power consumption during the formation of base vectors. The principle of symmetric pulse-width modulation (PWM) control on the operators of logical signal convolution is considered. The use of operators of logical signal convolution is a new scientific direction that allows effective solution of the problems of control of BLDC motors and simplification of algorithms of record of time-converting procedures.
