Abstract :
A high performance ac servo system with permanent magnet synchronous motor, including a field-weakening control and a high-speed current response control of PWM inverter is proposed. For the field weakening, the d-axis armature current is adequately controlled through a microprocessor. The novel current control scheme of PWM inverter includes the motor neutral point potential stabilization and the switching carrier frequency equalization.
