... Indirect Flux Control of Brushless DC Motorwith Non-sinusoidal Back-EMF without position sensor Abstract: In this paper, the position sensorless direct torque and indirect flux control ... conduction DTC of BLDC motor drive with six-switch inverter scheme. Keywords: Brushless dc (BLDC) motor, sliding mode observer, direct torque control (DTC), stator flux control, fast torque ... Block Indirect torque control method of BLDC motor explained in [9] was extended to a direct torque and indirect flux control technique for six-switch inverter BLDC motor in [7] which is suitable...
... accordance with the simulation result obtained in Fig. 8. Since only the torque is controlled without speed control, the time range of control system under transient state is selected short. The motor ... various cases with and without stator flux control, switch states 1 and 2, respectively in order to demonstrate the validity of the proposed four-switch DTC of a BLDC motor drive scheme with two-phase ... incremental encoder with 2048 pulses/revolution), therefore a good torque estimation can be obtained in (1).
