摘要
在有源功率因数校正(APFC)控制系统中引入模型偏差控制思想,采用模型偏差控制方法消除APFC系统在实际应用中的抖振问题,根据APFC状态方程得到PWM信号的占空比,并以单相Boost-APFC为例进行了Matlab仿真。仿真结果表明,采用模型偏差控制的APFC控制系统校正效果好,超调小,响应时间短。
The model deviation control method was applied in active power factor correction(APFC) to reduce buffeting of APFC system in practical application, the duty cycle of PWM was gotten according to the state equation of APFC,and single-phase Boost-APFC was taken as example to make Matlab simulation. The simulation results showed that the APFC control system with model deviation control method has good correction effect,small overshoot,and short response time.
