摘要
为解决永磁同步电机在阶跃响应中超调量太大的问题,设计了模糊PI控制器来实时调整其比例和积分增益,从而加快系统的动态响应性能。以Ti的TMS320F28335为控制芯片,详细阐述了嵌入式系统中硬件电路和软件程序的设计,包括相电流信号检测电路、速度信号检测电路、驱动电路、保护电路和模糊控制算法在中断函数中的实现流程。搭建了永磁同步电机模糊自适应控制系统,并进行了阶跃响应实验。根据实验结果可知,与PI控制器相比,模糊控制器可以将系统的超调量由30%降低到9%,验证了模糊PI控制器的有效性。
In order to solve the problem of large overshoot in the step response of Permanent Magnet Synchronous Motor(PMSM),a fuzzy PI controller is designed to adjust the proportional and integral gains in real time,so as to improve the dynamic response performance of the system.Taking Ti TMS320F28335 as the control chip,the hardware circuit and software program design of the embedded system are described in detail,including phase current signal detection circuit,speed signal detection circuit,drive circuit,protection circuit and implementation of fuzzy control algorithm in the interrupt function.The fuzzy adaptive control system of PMSM is built,and the step response experiment is carried out.According to the experimental results,compared to PI controller,the overshoot of the system using fuzzy PI controller can reduce form 30%to 9%,which verifies the effectiveness of the fuzzy PI controller.
