摘要
介绍了串联谐振变换器的最优轨迹控制法。首先分析了串联谐振变换器的4种工作模式,然后以谐振电感电流和谐振电容电压为状态变量,基于状态平面分析法推导了系统的最优轨迹控制法则。控制目的是使这两个状态变量跟踪他们期望的稳态轨迹,从而减少暂态振荡并在极短时间内达到稳态。实验结果表明,最优轨迹控制系统的暂态性能非常好。
The optimal trajectory control method of series resonant converter is introduced.Four operting modes are ana-lyzed,the resonant inductor current and resonant capacitor voltage are taken as state variables and the optimal trajectory control law is derived from the state-plane analysis method.The control goal is to force the state variables to track their de-sired trajectory.So the oscillation in transient process is reduced,and the steady state is achieved in min-mum time.The ex-perimental result shows that this method has superior performance especially under transient operation.
