RT 010 - 060 FUNDAMENTALS OF CONTROL ENGINEERING
Simulation of Controlled Systems The software features a simulation mode. This mode enables to also study controlled systems not covered by the real units.
Editing of Step Responses by Filtering and Decimation Real controlled systems usually have complex properties. The simulation mode enables elemental transfer functions to be entered and investigated. It is therefore possible to teach the fundamentals of control engineering in a simple way.
Identification of a real controlled system (RT 030) by the inflectional tangent method During recording of the step response a disturbance was repeatedly generated The determined controlled system parameters characterise the disturbed controlled system
Differentiation of the disturbed step response in “Filtering” mode Possible editing of the step response in two ways Integral behaviour
Activating a low-pass filter with input of the lower limit frequency Decimation with input of the increment
Differentiation of the step response after activating the low-pass filter and decimation Reduction of amplitudes by the low-pass filter
PT1 behaviour
Use of selected measured values (decimation)
Features of the Simulation Mode In simulation mode, the controlled system is defined by input of a transfer function Step response of the simulated controlled system is automatically displayed All software controller types can be applied to the simulated controlled system The behaviour of the simulated controlled system can be investigated in the same way as that of a real controlled system
PT2 behaviour
Step response with inflectional tangent after activating the low-pass filter and decimation Run of a curve is smoother compared to the unedited step response The new run of a curve causes a change in the determined controlled system parameters

USB connection
The RT 030 Pressure Control unit is still running.
In the software window „unit selection“, a mouse-click is all it takes to switch from RT 030 to RT 010.
The USB cable is removed from the RT 030 and connected to the RT 010.
The green frame indicates the active unit.
Now the RT 010 Level Control unit can be used.
Teaching scenario: The tutor highlights an interesting variation in time occurring on the RT 030 Pressure Control unit to explain it to the whole group.
