Abstract
In modern control systems, the quality indicators of the control process are divided into direct and indirect. Direct quality indicators include properties determined by the transient characteristics of the system. Indirect quality indicators include root, frequency and integral indicators. The possibility of applying quadratic integral quality criteria for automatic control systems has been considered in this work. The analysis is carried out for the possibility and expediency of using such a criterion in digital control systems built based on software and hardware complexes using the principles of optimal control. To perform this analysis, an automatic control system with a classical proportional-integral regulator is considered. The function of calculating the instantaneous and integral quadratic and root-mean-square criteria of the desired controlled parameter from the real signal at the output of the control object has been added to the algorithm of this system. The criteria have been calculated throughout the entire transition process, as well as at each period of the controller call. Then, the results obtained are compared. The possibility of applying integral quality criteria in digital control systems built on the basis of software–hardware complexes has been demonstrated.
