PIDMA - PID controller with pulse autotuner


The simulator demonstrates the features of PIDMA function block - PID controller with pulse (moment) autotuner. The tuning algorithm is based on estimation of three impulse response moments. Firstly, both drift and noise of process variable are estimated. Then the rectangle pulse is applied. From the pulse experiment, the process model is build internally using three impulse response moments. Finally, the robust PID controller parameters are computed from the internal tables. The simulator demonstrates the PID loop tuning including noises. The detailed description of PIDMA block is available in the reference manual.

How to start the simulator?

Before starting the simulator 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.
