Based on the Repetitive Controller for Induction Heating Power Supply

Abstract:

According to the electromagnetic induction heating power supply control system, puts forward a kind of proportion, integral, differential regulator with repetitive controller combined control strategy, in order to improve the heating process of the power supply output quality. Based on this control strategy, gives the repetitive controller each part parameters of the detailed design scheme and proportion, integral and differential controller coefficient; Construction of compensator Q(z) and S(z) , the introduction of zero phase shift Notch function, effectively inhibit PWM-type induction heating power supply output voltage harmonic interference. To carry out the simulation experiment, the results show that the proposed controller can guarantee that the system has better dynamic and static properties, error convergence rate is greatly improved.
