Fuzzy non-ideal proportional-resonant controller with no dead time strategy for variable frequency constant current power supply
摘要
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 u-sing 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 problems caused by dead time are eliminated by designing the no dead time strategy; The fuzzy controller is used to shorten the dynamic response time of the power supply and improve its reliability, and makes the current tracing reference fast in the first period. The simulation results show that in the case of inductive load, the power supply using all these methods has the advantage of no static error in tracing AC reference, small harmonic components, fast dynamic response, etc. As a result the power supply can provide a good current output to meet the requirements of variable frequency constant current experiment.关键词
