Dtc Pmsm Thesis
In this proposed simulation diagram sensor less speed control for pmsm. In that system can be estimated the rotor speed and simulate with matlab software. 8 shows the block diagram of speed sensor less control of pmsm based on dtc method with adaptive system. In this thesis, the mathematical model of pmsm and two popular control strategies, field. 3 simulation model of dtc of pmsm.
These are permanent magnet synchronous motor drives and brushless dc motor. The pmsm had a sinusoidal back emf and required sinusoidal stator currents which produced constant torque while the bdcm had a trapezoidal back emf, required rectangular stator currents for producing constant torque. 34 upc pmsm control. Permanent magnet synchronous machine.
Dtc is a sensorless technique which operates the motor without requiring a shaft mounted mechanical sensor. It is suitable for control of the torque and flux without changing the motor parameters and load. In this method torque and stator flux are directly controlled by two hysteresis controllers. Design, simulation and implementation of a pmsm drive system thesis for the degree of master of science in engineering david vindel muñoz division of.
This thesis obtains the modelling of the direct torque control. System of pmsm using matlab. Speed control of pmsm using field oriented control technique and direct torque space vector pulse width modulation technique is also analysed and compared with traditional dtc. In this thesis, the mathematical model of pmsm and two. This thesis aims to reduce the torque ripple in the dtc based pmsm drive by using the new.
