SMHCCA - Heating cooling temperature controller


SMHCCA simulator demonstrates the features of temperature controller for heating-cooling processes with highly non-symetrical binary actuators. In this case the PID controller gives not sufficient results. The controller is based on sliding-mode principle. The main advantages are easy tuning (block provides autotuning feature) and high temp control quality. The block features are demostrated on a simple plastic extruder model. The block description is available in the reference manual.

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.
