| description | Steam temperature control significantly affects the efficiency, reliability and durability of steam boilers. In the article, special attention is paid to substantiating the relevance of a significant increase in the efficiency of steam boiler injection regulators operating in a wide range of load changes. It is indicated that one of the main directions of solving this problem is the use of optimal regulators with dynamic compensation and combined principles of regulation for deviation and perturbation at the same time. A combined automatic control system is proposed with full invariance with respect to the most dangerous measured internal disturbance and with partial invariance when working out an external disturbance with specified permissible deviations of the controlled parameter. At the same time, in order to improve the quality of regulation under the main influences, it is proposed to carry out optimization with the use of the transfer functions of the leading and main sections of the control object as well as to turn the internal contour of the two-circuit system into an amplifier with a single transmission coefficient when working out the corrective action. Also, it is proposed to form the structure of the corrective regulator on the basis of the principle of dynamic compensation for objects with a conditional delay along the channel of regulatory action, which makes it possible to ensure the specified quality of regulation when working out the control action surge. Thus, a significant increase in speed and accuracy is achieved when working out internal and external measured disturbances compared to a typical two-circuit system or an invariant automatic control system with an internal model, which makes it possible to recommend the proposed invariant cascade automatic control system for widespread implementation in the field of automation of thermal power processes. |
