Pulse-width modulation (PWM), or pulse-duration modulation (PDM), is a modulation technique used to encode a message into a pulsing signal. Although this modulation technique can be used to encode information for transmission, its main use is to allow the control of the power supplied to electrical devices. This paper proposes the PWM control of the laboratory bell furnace with utilization of PI controller. The paper presents the PI control algorithm modified in order to regulate the power of furnace. The control is focused on temperature stabilization in furnace or in batch. The main problem is that the proposed furnace does not enable continual control the power. There is possible just On-Off control with a digital signal. Paper present how to transform the PI controller output into the PWM control actuating. There was utilized PLC as a main controller of furnace. The control algorithms were proposed in B&R Automation Basic language as a cyclic tasks implemented on PLC. The proposed experimental furnace was used in order to simulate the annealing of steel coils and verification of indirect measurement of temperature.
