Simulation of direct torque control of permanent magnet synchronous motor and implementation of drive system

By advancements of permanent magnet synchronous motors (PMSM) along with technology, they have been frequently used in industry and renewable energy sources applications because of their superiorities on parameters such as efficiency, power factor, and power-weight ratio with their too little necessity of maintenance.As using SMSM?s with advanced drivers, only requested operation can be achieved from the motor. In this way, by eliminating the extra energy expenditure good result in term of energy efficiency can be achieved.Need of control on speed and torque comes forward on general applications. Within past years there have been lots of developments in control techniques on purpose of meet this requirement. In this study direct torque control technique of permanent magnet synchronous motor is suggested. For that reason simulation model of direct torque control technique of permanent magnet synchronous motor has been implemented on MATLAB/Simulink platform and examined its results.Also in this study, in purpose of use of further studies a digital signal processor (DSP) based drive mechanism has been designed and implemented. Digital signal processors are used in the purpose of quick determining combination of the inverter switches for desired control technique. So that the desired response from the system will have been obtained with an acceptable delay.
