PID Self-Tuner
Loadable function blocks for self adjusting controllers
Description
The PID Self-Tuner software package expands the PID controller with additional function blocks to form a self-tuning PID or PI controller:
Easily understandable functions and systematically structured examples enable the controller to be adjusted online and adapted to the process.
PID Self-Tuner can be combined with PID Control (integrated into STEP 7), Standard and Modular PID Control as well as FM 355 and FM 455. PID Self-Tuner can be used on SIMATIC S7-300/400 and C7 hardware platforms as well as in WinAC. PID Self-Tuner is ideally suitable for optimizing temperature, fill-level and flow controls.
Process requirements
Stable asymptotic transient response Delay times that are not too long (delay time < 0.3 x build-up time)
Sufficient linearity in the selected operating range
Sufficient quality of measurement signals
Processes are not intensified too much

Online initial adjustment of PID controllers
Online adaptation of the PID controller for reoptimizing at the operating point
Optimizing processes with heating and active cooling
Manual mode
