Controller structures
Construction of a It may be simple – e.g. P-controller or PT1 controller, etc. – or complex (e.g. state control or adaptive control ).
Self-tuning controllers
Automatic controller settings with self-teaching systems or identification processes or similar methods. The self-tuning of controllers is intended to accelerate difficult and arduous initial settings
control parameters
Setting values of the controller, which can be used to adapt the controller properties to the conditions of the controlled subsystem, and the quality requirements of the .
Optimising the controller
A controller, in fluid technology must be configured through fine tuning of the various parameters (e.g. P-component, I-component, etc.) or for state controllers of the amplifiers such that the system
Controller concepts
Among the numerous possible controller functions for constant those involving basic transfer elements ( transfer elements ) are the broadest. These include: P-controller [P-controller]: Each control d
Controller settings
Adaptation of controller properties to the respective task by changing the control parameters with the aim of optimising the controller .
Controller input variable y R
Variable present at the controller input. To distinguish it from the control variable it is given a subscript R. The controller input variable is rarely identical to the control variable x. In general
Controller output variable y R
Variable issued by the controller output. To differentiate it from the correcting variable, it is given a subscript R (DIN 19 225). The controller output variable is only the correcting variable which
Controller types
According to DIN 19 225, controllers are divided according to their tasks and properties. Designation according to tasks distinguishes between the type of the controlled variable , such as the locatio
Control amplifier
Activation amplifier for high response proportional valves ( Figure R 19 ). has largely the same functionality as proportional amplifiers for position-regulated proportional directional valves.
