Abstract
- This paper examines the control performance of permanent-magnet synchronous motor drive systems based on current control and direct torque control (DTC) when flux-weakening control is applied. The control law in the M–T frame, which is used in the DTC, requires only armature resistance, whereas the control law in the d–q frame, which is used in current control, requires many motor parameters for flux-weakening control. The experimental results clarify the influence of parameter variation on the control characteristics of flux weakening and torque limiting. The DTC-based motor drive system combined with the control laws in the M–T frame has several advantages, including insensitivity to parameter variation, simplicity of calculation, and stable control.
