This paper presents a simulation study using Matlab introducing Direct Torque Control (DTC) method which is implemented on BLDC motor. BLDC motor is well known and has been widely used in the industrial area due to the high speed and power density. Electronic commutation is by far more favourable compare to the conventional DC motor which uses brushes and commutators that wears and tears by time. However, a precise controller is required in order to control the switches prior to commutation process. DTC of BLDC combines a simple control method and a demanding motor to complete a better drives system. Based on in depth analysis of BLDC mathematical model and the operation of DTC system, a simulation model is developed using Matlab/Simulink. The capability and performance of torque and flux control of the drive system is verified.read more

Analysis of direct torque control in permanent magnet synchronous motor drives
TL;DR: In this paper, direct torque control (DTC) for permanent magnet synchronous motor (PMSM) drives has been investigated, and it is proved that the increase of electromagnetic torque in a permanent magnet motor is proportional to the angle between the stator and rotor flux linkages, and therefore the fast torque response can be obtained by adjusting the rotating speed of the stators flux linkage as fast as possible.
