The development of simulation model of servo system for melt jet flowing from the furnace is considered in this paper. The system is dedicated to maintaining the angular value of TV camera sight line. The camera follows the melt jet flowing from the furnace so the system has to control the rotation of the motor shaft connected with the camera. The dynamic simulation method is used for the system description. Such an approach allows determining the optimal control law and the PID parameters in order to improve servo system characteristics.Optimal controller parameters were found using the Simulink Response Optimization toolbox. The characteristics of the simulated system are analyzed on the basis of its block diagram. The analysis of the stability of the servo system is made using the Nyquist criterion. The results of the dynamic simulation of the servo system are illustrated by Bode diagrams.
