| Popis: | 104 The thesis investigates the design and implementation of an interior permanent magnet synchronous motor drive system. First, a predictive speed controller design is proposed. Next, a auto-tuning flux weakening control, which doesn’t require any motor parameters, is proposed. The voltage of the motor is feedback. When the motor voltage is higher than the dc link voltage, an advance current angle is online adjusted to execute the auto-tuning flux-weakening control. A digital signal processor, TMS320F28335, is used to execute the speed controller and flux-weakening control. Experimental results validate the correctness and feasibility of the proposed methods. The proposed system includes a wide adjustable speed range, fast transient response, good load response, and good tracking response. |
