In this paper the implementation of the vector control systems for a variable-speed 4088kW PMSM (Permanent Magnet Synchronous Motor)in ship electric propulsion systems has been studied. At the basis of analysis of the mathematical model of the PMSM and the principle of vector control, two methods for modeling and simulating of PMSM system based on the Current Hystersis PWM (Pulse Width Modulation)...
The basic principle of space vector pulse width modulation (SVPWM) and a method of building two closed-loops vector control simulation model for permanent magnet synchronous motor (PMSM) are presented in this paper. At the same time, a new non-linear PID controller in speed closed-loop is studied. Simulation results show that it has good dynamic and static performances with no overshoot and small...
The continuous improvement of social practical production demands modern motor controlling technology. PMSM has been widely applied to those occasions of high performance because of its excellent performance. However, there are large flux linkage and torque ripples and inconstant switching frequency in the conventional DTC. To solve these problems, PMSM DTC using SVPWM based on the subdivision of...
