FIELD: automation of technological processes, possible use in chemistry, metallurgy and other industrial branches. ^ SUBSTANCE: temperature controlling method, in accordance to invention, includes deciding on a temperature setting and measuring current temperature, calculating value of deviation between current temperature and set temperature, calculating speed of deviation value change and creating setting signal for executive mechanism. In accordance to invention, a task for executive mechanism is formed a total of setting signal and perturbation correction signal. Perturbation correction signal is formed by means of first fuzzy logic block and recorded in time moments determined by second fuzzy logic block. In accordance to output value of second block of fuzzy logic, either current perturbation correction signal, or correction signal, stored in memory, is dispatched for addition. Temperature control system contains deviation block, first and second inputs of which are connected respectively to temperature setting input and temperature sensor output, and a differentiator, input of which is connected to deviation block output. In accordance to invention, system contains block for transforming temperature setting to setting signal, input of which is connected to temperature setting input. Added to the system are the following components: first fuzzy logic block, first and second inputs of which are connected respectively to output of deviation block and to differentiator output, and second fuzzy logic block, first and second inputs of which are connected respectively to output of deviation block and differentiator output. System is also supplemented with memory block, first and second inputs of which are connected respectively to output of first fuzzy logic block and output of second fuzzy logic block, selection key, first, second and third inputs of which are connected respectively to output of memory block, to output of first fuzzy logic block and to output of second fuzzy logic block, and to adder, first and second inputs of which are connected respectively to output of block for transformation of temperature setting to setting signal and to the output of selection key. ^ EFFECT: increased precision when controlling given temperature in heating chamber of a furnace. ^ 2 cl, 13 dwg |
