Abstract
This article provides an analysis of the control object, considers factors that complicate the achievement of maximum quality stabilization of the threshing machine loading, including the dynamic characteristics of the elements of the control object, the dynamic characteristics of the disturbances acting on the control object.
To achieve the maximum quality of stabilization of the threshing machine loading of a combine harvester, it is necessary to apply methods of dynamic design and analytical construction when building an optimal system. Before developing the system, it is necessary to analyze the factors, the consideration of which will allow achieving the required quality. These factors can be divided into three groups: dynamic characteristics of the elements of the automatic stabilization system; dynamic characteristics of disturbances acting in the system; noise of the meters.
From the point of view of dynamic characteristics, the most complex element of the system is the control object, the input of which is the angle of inclination of the washer of the hydraulic pump cylinder block, and the output is the flow of grain mass at the entrance to the threshing machine. From the position of the problem of stabilizing the threshing machine loading, it is necessary to obtain a model of a generalized control object, namely, the dynamic characteristics of the elements of the control object, the dynamic characteristics of the disturbances acting on the control object
Each component of the control object is a rather complex mechanism, which is affected by complex stochastic external and internal influences. It is quite difficult to obtain an analytical model of the dynamics of the control object, which, on the one hand, would be simple enough to successfully solve the problems of developing a control system, and on the other hand, would take into account the main factors affecting the quality of the process of stabilizing the flow of grain mass in real operating conditions. Therefore, to solve the problem of stabilizing the flow of grain mass, it is proposed to use the experimental-analytical concept of determining the model of the dynamics of the control object and the disturbances acting on it.
