TECHNOLOGICAL PROCESS CONTROL CAPABILITIES

The modern definition allows us to interpret the technological process as a complex system in interaction with the components of the environment, which leads to a beneficial effect. From this point of view, the technological process is subject to the general rules of control theory, thanks to which the principles and algorithms used in this theory can be adapted and extended to the control of technological processes. It is noted, however, that the main difference between the technological process and traditional control objects is the constant irresistible and degradative change in its characteristics over time. The article shows the possibility of transition from process control in the statistical sense to control in terms of the actual state, i.e. to real-time process control. The concept of functional controllability of technological processes is introduced. An analysis of the generalized block diagram of the technological process control system as a technically complex system is given. The formalization of the goals of technological process control is given, which makes it possible to form further control tasks and typical control schemes for specific technological operations. It is demonstrated that these theoretical guidelines play a crucial role in the current shift from analog to digital control of technological processes.
