The article describes the process of creation of an adaptive control system with a reference model to stabilize the temperature of drying agent. It is shown that the closed systems work with the operated models is quite satisfactory and therefore can be implemented in production. The increase of the gain of the controller allows reducing the duration of the transition process by one third, almost without changing the dynamic cast
In the article, the analytical way of working out of mathematical model of process of heating of air for grain drying is shown. It is considered, that the temperature of a wall influences on dynamics of process of heating. Dynamic characteristics of the top internal device are considered. With use of package Mathcad schedules of transitive functions on operating and revolting influence are received. Results of modeling are presented
The article considers the issues of digital process of control of heating air in the dryer shaft
In the article we present questions of digital process control of heated air for drying seeds; it is shown that the change in the load of the heat source slightly changes the dynamics of the system for stabilizing the temperature of hot air, making it almost invariant with respect to perturbations. It is proved that the use of digital controller with dual differentiation significantly improves the performance of the automatic control system, excluding the increase astatism of the management system
The article is devoted to the point of optimizing the sys-tem of digital control, containing an engine. It is also devoted to the point of applying different laws of control. There are submitted practical recommendations on using the digital controller with double derivation
The article is a study of digital continuous system and
optimization of digital control systems. It is shown that
the standard in the synthesis of digital systems should
provide a continuous system, so first we need to create
the desired continuous system and then we could try to
get the digital system closer to it
In the article, the basic problems which experts in management at synthesis of digital systems of stabilization of parameters of technological processes face are shown. The exact samples of optimization of parameters of a regulator and reception of discrete models of digital devices are resulted; the comparative analysis of continuous and digital systems is given
The article presents the recommendations for a process control system of heated air for drying seeds. The problem of selecting a control device is solved. The calculations of transfer functions of the closed ACS are made. The optimal controller gains are found.
The article considers the issues of digital process con-trol heating air in the dryer shaft
The article considers the problems of determining the
settings area of the control device, which ensure stable
operation of the closed system. It shows the solution to
the problem using the enhanced amplitude-phase characteristics.
The proposed method of finding the domain
of stability of parameters of the control device is
more simple than classical methods and allows, in
general, to find conditions for the stability, not to test
the system for stability under given parameters
