| 摘 要： | 针对变压器振动频响法所进行的变频恒流试验的需要,提出了无死区的模糊准PR控制的变频恒流源的设计.利用准PR控制,跟踪给定的参考电流信号,实现了稳定电流输出的同时消除了PID等控制所存在的静差误差问题；设计了无死区策略,消除因为设置死区时间而引起的谐波含量过大的问题；同时引入模糊控制算法,结合准PR控制,实现初始电流的快...

| Abstract: | In order to satisfy the need of variable frequency constant current experiment for transformer vibration frequency response analysis,a variable frequency constant current power supply using fuzzy non-ideal PR(proportional-resonant) controller with no dead time strategy is designed.Using the non-ideal PR controller makes the current tracking AC(alternating current) reference without error in magnitude and angle which exists in the PID(proportion integration differentiation) controller;The excessive harmonics... |
