The article substantiates the need for technical monitoring of automatic control systems and suggests a method for supervising their technical state based on the example of speed controllers in internal combustion engines. The causes of occurrence and negative impact of irregular rotation rate on the efficiency of power plant use are described. The main diagnostic parameter characterizing the regulation quality should be the behavior of the automatic control system in a dynamic transient process when a single multistage disturbing effect enters the system input. As such an effect, it is proposed to use crankshaft angular acceleration during internal combustion engine free acceleration. The results of theoretical and experimental studies confirming the validity of selected engineering solutions are presented. It is proved that maximum crankshaft angular acceleration negative value in the oscillatory transient during completion of engine free acceleration depends on the degree of speed controller non-uniformity, which determines the deterioration rate of its parts and the state of the adjustment parameters. The significance of regression equation coefficients, which describe the obtained interdependence, is confirmed, and a device for monitoring technical state of automatic speed control systems is developed. The proposed method of supervising the technical state of speed controllers ensures the implementation of remote technical monitoring and contributes to improving operation efficiency of transport vehicles and technological equipment.
