PSMPC - Pulse step predictive controller

You need to have Java installed to run the virtual labs. Click the Launch button to download the lab installer to your computer. By clicking on the downloaded JNLP file, the lab will be automatically installed and launched. Virtual labs use Java Web Start technology.


PSMPC simulator demonstrates the features of pulse step model predictive controller (MPC). The function block is designed for high quality control applications where the control actions are limited. Predictive control is applicable even for difficult to control processes with dominant dead-time of non-minimum phase. It is suitable for cases where the fast step response without overshot is required. PSMPC can substitute traditional PID controller in lower level predictive control systems. 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.
