Stepping controller

It is necessary to install Java and import our certificate for Java applets to run the virtual laboratories. A step-by-step tutorial is available.

Stepping controller

Stepping controller example shows connection of the PID controller (PIDMA - PID controller with moment autotuner) to the servo-valve without position feedback. Function block SCUV estimates current position and velocity of the valve. The servo valve is represented in this example by MVD block and process with large time-delay. This strategy is often called as increase-decrease control.

How to start the simulator?

Before starting the simulator (applet) by START start.gif, 648B button, the sampling period can be set in the field Sampling time. The continous applet running can be stopped by STOP stop.gif, 666B button or paused by PAUSE pause.gif, 1,1kB button. The simulation speed can be adjusted by the slider. The re-init button reinit.png, 858B reset all parameters to initial state.

All parameters of active blocks (non-shadow) can be changed in the dialog which is invoked by cliking at the block. Detailed description of block parameters is available in Function blocks reference manual.
