CONTROL OF THE HEATING INSTALLATION TEMPERATURE FIELD IN THE FORM OF FRACTIONAL-ORDER MODEL

Was developed and implemented the device for controlling the temperature mode of heating system in the form of fractional order model in the technological process of sapphire crystal growing. As it is illustrated in article the usage of fractional control laws of PWM increases the system quality. And also is shown that using of FET properties of significantly increasing the value of able current in the short-pulse mode led to the possibility of implementing a flexible control for large capacity.
