摘　　要：为提高远端稳压电源的供电质量,最大限度的在高可靠性前提下保证发射设备输出电压快速、平稳地达到设定值,提出一种改进反激拓扑模式下远端稳压电源设计方式,并建立相应数学模型。设计了前置论域整定的模糊比例积分微分(PID)控制算法,通过论域整定模型将模糊PID参数直接映射到模糊规则下,消除试凑法偶然性的同时消除了量化因子对误差的放大作用,有效地避免了过度调整的现象;引用模糊逻辑来实时处理远端稳压电源的动态参量值,并根据反模糊映射函数将生成的量化值映射到控制元件。仿真环境模拟结果表明:与模糊PID控制相比,前置论域整定的模糊PID控制算法具有优良稳态性能,调节时间缩短48.1%,响应时间缩短了28.6%并降低到1.4 ms;与此同时,该控制方案能够有效地抵抗突发性干扰,稳压输出时间缩短了45.5%,响应时间缩短到37.5%。实验结果表明:前置整定模糊PID控制算法可以运用到实际工业环境中,与工业环境下传统控制算法比,前置整定模糊PID控制算法可以大幅提高远端稳压电源的供电质量,具备优良的鲁棒性。In order to improve the power supply quality of the remote regulated power supply and ensure that the output voltage of the transmitter device reaches the set value quickly and smoothly under the premise of high reliability,a design method of the remote regulated power supply in the flyback topology mode is introduced,and the corresponding mathematical model is established.Here,a fuzzy proportional-integral-derivative(PID)control algorithm for pre-domain tuning is presented.It uses fuzzy logic to process the dynamic parameter value of the remote regulated power supply in real time,and it maps the generated quantitative value to the control element in accordance with the anti-fuzzy mapping function.This effectively avoids the phenomenon of over-adjustment and eliminates the accidentality of the trial method and the amplification effect of the scale factor on the error.According to simulation results,the fuzzy PID control algorithm with pre-domain tuning performs better in steady-state conditions than the fuzzy PID control algorithm without pre-domain tuning.The adjustment time,response time,and reduction to 1.4 ms are all shortened by 48.1%,28.6%,and 37.5%,respectively,while the control scheme is also able to withstand abrupt interference with good effectiveness.The experimental results show that the pre-tuned fuzzy PID control algorithm can be applied to the actual industrial environment,and compared with the traditional control algorithm in the industrial environment,the pre-tuned fuzzy PID control algorithm can greatly improve the power supply quality of the remote regulated power supply and has excellent robustness.
