Realization of adaptive regulators in distribution control systems

The article considers the problems of synthesis of different distributed controllers and methods for implementing the adaptation the system of these controllers. Each type of distributed controllers has its own parameters in the transfer functions. The parameters of the controller can be obtained after studying and identification of the distributed control object. In the transfer functions there are two parameters that can be changed in order to achieve the high-quality transient processes in the control system. These parameters are: weight coefficient of the distributed link ni and the proportionality coefficient of the distributed link Ei. The parameters of the distributed link G and s depend on the object structure and on the time (or the selected sampling interval of the digital controller), respectively. According to the results of the synthesis of parameters of distributed controllers, there have been proposed the methods for implementing adaptive setup of different controllers. Currently, the following controllers are available: distributed high-precision controller, space-amplifying controller, space-differentiating amplifier controller, spatially-isodromic controller for distributed control systems. There has been considered implementing a distributed controller and shown in which part it is necessary to be adapted. The controller type is selected according to the tasks to be solved by the distributed object control system. Depending on the controller type, in the implementation of controller blocks, there can be used the standard integration and differentiation blocks available in different programming languages for programmable logic controllers. The example given in the article was developed using the CoDeSys software package supplied with OVEN programmable logic controller.
