Induction Heating System

In this work, the dimensions of a furnace for melting of ferrous alloys were determined. The furnace has an electromagnetic induction heating system. In addition, the parameters of electrical power supply such as frequency and power were calculated. A 5kg cast steel mass with a density of 7.81 kg / dm3 was proposed. This corresponds to a crucible volume of 0.641 dm3. The frequency was obtained from tables, which take into account the diameter of the crucible, and its value was 1 KHz. The energy consumption was determined with the heat required to bring the steel to the temperature of 1740 K, the energy losses through the walls, bottom and top of the crucible. This value was divided between the heating time (30 minutes) and resulted in a power of 4.5 KW. The development of the calculations shows that the induction heating is an efficient process and allows a fast melting of ferrous alloys.

Repetitive Controller

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.
