The new strategy of hybrid control system constructing for the basalt superfine fibers production plant is developed; it includes the classical control system with deterministic feedback in the circle of primary windings current regulator of the filier feeder transformer, filier feeder temperature proportional-integral fuzzy logic controller that provides required temperature value stabilization, indirect control of the feeder temperature current value T and the change rate T / ?t and includes fuzzy logic controller of BSTV primary fibers diameter which provides interconnected adjusting the threads pulling speed and the filier feeder temperature, depending on the thread diameter, feeder operating time and the melt temperature in the furnace of BSTV plant; the new method of fuzzy logic control of the BSTV installation is developed, under the unpredictability of technological parameters changing of the BSTV system, the control system based on the knowledge base of the three criteria (required diameter of the primary thread, the continuous operation time of the BSTV installation and the basalt temperature) forms the control signals - speed of the primary fiber pulling and current of the primary windings of the filier feeder transformer; the topology of the combined filter-compensating devices (FCD), which includes passive LC filter and current form correctnr in the thyristor current regulator - special transformer (TCR-ST) system is proposed, combined FCD reduces the total harmonic distortion THDI from 74% to 9.5% in the filier heating mode and in the working thermal mode of the filier feeder (current stabilization mode of the transformer primary winding) - from 31% to 19%; new approach to the formation of the TCR-ST system is proposed, it combines the advantages of the CT with solderings and the current-type corrector hybrid structure, and reduces the corrector power by 34%, and the cost of such FCD becomes acceptable for further use in power supplies of electrothermal plants for the BSTV production; the control strategy with the use of scalar sliding modes is developed, which allows obtaining high quality of processes (zero static and minimum dynamic error) for forming the output voltage and current of the MP load, reducing the mass-dimensional parameters of the input smoother LC filters (by capacitance of capacitors - up to ten times ) in comparison with traditional one, designed for canonical harmonics; new vector algorithms for generating the output voltage in the sliding mode is developed, which enable to obtain the maximum output performance of output voltage circuit of the matrix converter MP and the maximum time between the two subsequent in time stationary states of the MP; new control strategy with the use of switching bans is developed, instead of generating in control system of complex trigonometric injection functions for reducing the switching frequency, which allows to simplify the hardware and software implementation of the MP control; new vector approaches with the use of simplex algorithms are proposed, which allow receiving input power factor close to unity and the input current form close to the sinusoidal one. Practical schemes of hybrid control systems with fuzzy logic, means and algorithms for controlling voltage, current and frequency are created. This allowed the implementation of 5 voltage regulators RENAP-3T-150 intended for current controlling on the active element of the heating furnace and keeping the temperature at the level necessary for the efficient and accurate execution of the technological process in the units of the model KL209; 8 voltage regulators RENAP-1T-100DT intended for automatic control of current in the primary windings of transformers ТВК-75 (current of the filier feeder) and maintaining the filier temperature at the level necessary for the effective and accurate formation of the length and diameter of the primary fiber in plants for the production of basalt ultra thin fibers UBSTV-42.
