| Abstract |
An improved simulation model has been developed for predicting the dynamic performance of vectorcontrolled
permanent magnet brushless ac drive systems on the Simulink/Matlab environment, with
particular reference to their field-weakening performance. It caters for the characteristics of brushless
permanent magnet synchronous motor and alternative field-weakening control and PWM strategies,
etc. In addition, it accounts for the effect of magnetic saturation, e.g. the dependence of winding
inductances on the currents, and is capable of real-time compensation of the effect of winding
resistance etc. The predictions are validated by experiments made on a DSP controlled drive system.
The simulation model is then used to investigate the transient and steady-state dynamic performances
of an interior magnet brushless ac motor in both constant torque and constant power operation ranges. |
