Abstract

Technological progress is impossible without creation of the advanced technologies, machines, materials, as well as automation tools. Automationdevelopment in any industry is associated with the increasing intensity of technological processes, application of high-power units, sophistication of technological schemes and increased requirements for the produced items. Today, automation of technological and production processes is an urgent task for most enterprises in all industries. This work analyzes the technological process of service water preparation, shortcomings reducingprocess water selectionquality regulationwere found, a search for existing solutions improving the process water quality and labour safetywas made. The water level converter in the tank is taken as an ideal proportional link without inertial delay in signal transmission.The software controller operates according to a PD control algorithm (proportional-differentiating controller).This provides the control system with the required speed, i.e. a prompt response to changes in the mismatch between the specified and actual water levels in the tank.Thus, the synthesis problem is localized by choosing the coefficients of the proportional Kp and differentiating Kд components of the controller.To assess the relevance of optimal value selection of the proportional and differentiating component coefficientsof the regulator, a simulation model of the automatic control system was developed.The simulation model implements all structural connections of transfer functions and calculated coefficients.During simulation experiments, the optimal values of the controller coefficients were confirmed for the described conditions.Technical means of automation were selected, a mathematical model for controlling a valve with an electrical drive was developed, and a block diagram of a system for automated control of the water level in the tank was developed, a level controller has been synthesized, providing the effective monitoring systemimplementation with regard to the technological process.
