摘要
针对移相全桥开关电源系统的复杂性、时变性以及传统比例积分微分(PID)算法难以满足控制要求的缺点,提出采用模糊比例积分(PI)和模糊比例微分(PD)相结合的控制方法。该方法不依赖系统数学模型,可对控制参数进行在线整定。通过Matlab/Simulink搭建系统模型,确定模糊控制规则,仿真结果表明该方法对开关电源系统具有较好的控制效果。将其应用在基于现场可编程门阵列(FPGA)的数字控制器中,实现了对1.2 kW移相全桥开关电源样机的有效控制。
Against complexity and time-varying of the phase-shifted full-bridge switching power supply system, the tra- ditional proportional integral differential（PID） algorithm is difficult to meet the control requirements.The control method which is combination of the fuzzy proportional integral （PI） and fuzzy proportional differential （PD） is proposed, it does not depend on the system mathematical model,and it tunes control parameters on-line.Building a system model by Matlab/Simulink to determine the fuzzy control rules, and the simulation results show that the method for switching power supply system has better control effect.The method on field-programmable gate array（FPGA） controller is im- plemented on a 1.2 kW phase-shifted full-bridge switching power supply prototype effectively.
