摘要：
The variable frequency speed control is one of the most important issues for fan filter unit (FFU) system. A novel digital variable frequency control system for FFU motors were proposed and developed to decrease running losses, and improve the speed control effect and accuracy. The system uses high-performance digital signal processor (DSP) TMS320F2812 as the control core, which adopts a dedicated motor pulse width modulation (PWM) control module to achieve the FFU motors' real-time online digital variable frequency control. The composition and working principle of control system were illustrated, the hardware and software design were illustrated in detail. Finally, the experimental results on control system prototype were given, which confirm the effectiveness and validity of the control strategy, and demonstrate that the proposed method can achieve accurate variable frequency speed control of FFU motors.
