In this paper, to achieve high-precision steady state waveform and fast dynamic performance, a new control method is introduced, namely, a two-tier structure, the traditional digital PID controller and repetitive controller working in parallel. We name it as hybrid controller. Response speed between the two kinds of control methods is different and the time is decoupled. This control method can restrain...
In order to satisfy the higher control performance requirement of the induction heating supply, a fuzzy logic control technology for induction heating power supply power control system is researched. This study presents the composition and design of the induction heating control system based on the fuzzy logic controller. In this paper, a complete simulation model of induction heating systems is obtained...
In synchronous rotating frame (SRF), the mathematical mode of a three-phase PWM VSI with LC filter is complex, and the dq components have cross coupling terms. In order to obtain good dynamic and static performance, the controller structure should be inherently based on the systempsilas mathematical model, which means that the decoupling control strategy with feed-forward should be adopted. But this...
