• Dynamic performance
• Start up
• Voltage model

Flux estimation plays an important role in induction motor control system, which has directly influence on the performance of the system. In order to improve the dynamic performance of PCLPF, a novel method (modified PCLPF) is proposed, which improve the dynamic performance (especially the low speed performance) of PCLPF by exchanging the order of compensation and low-pass filter. The reason for performance improved is analyzed theoretically, while the validation and effectiveness of the new method are verified by simulations and experiments. On the other hand, a new method is studied to solve the start-up problem associated with MPCLPF.
