Analysis of Direct Torque Control of PMSM Drive Using Different Inverter Topologies
نویسندگان
چکیده
Permanent Magnet Synchronous Motor (PMSM) drive is being preferred in industrial automation due to high efficiency, compact structure, and high torque to weight ratio and so on. PMSM have been widely used in variable speed drives. The direct torque control (DTC) technique for a PMSM motor is receiving increasing attention due to the important advantages as the elimination of the current controllers and the low dependence on motor parameters when compared with other motor control techniques. The basic theory of operation for the control technique is presented. A mathematical model for the proposed DTC of the PMSM topology is developed. A simulation mode developed in MATLAB/SIMULINK is used to compare the performance of the PMSM drive using different inverter topologies.

Tracking control of the direct-drive robot manipulators in high-speed is a challenging problem. The Coriolis and centrifugal torques become dominant in the high-speed motion control. The dynamical model of the robotic system including the robot manipulator and actuators is highly nonlinear, heavily coupled, uncertain and computationally extensive in non-companion form. In order to overcome thes...
