Quality assessment of induction furnace control for biomass ash fusibility determination

The quality of the control of an induction furnace for the determination of ash meltability at high temperature by the tube method was evaluated. For this purpose, the dynamic characteristics of the control object were measured and recorded on the test stand. The characteristics was the basis for developing a simulation model of the object. This model was tuned and its correspondence to the object was confirmed by computer simulation. Based on this model simulation models of the control system were created in the configuration with controllers, parallel PID and PID+DD. During subsequent computer simulations, control parameters were determined and the effect of the noise signal on the modelled system was evaluated. To evaluate the quality of the control, integral quality indices were used.
