User Manual For - CONTROLLER/DATA RECORDER MultiCon CMC-99/141
PID controller configuration
The PID controller configuration can be done in two ways: manual and automatic. In
manual mode, the user defines all factors and additional elements of the controlers (fuzzy
logic,
Inertia
, output limitations,
Dead zone
) at its own discretion. The settings chosen by the
device in automatic mode can also be improved and fine-tuned. It is possible to disable each
block of the PID Controller and additional blocks.
In automatic mode the device is in the process of autotuning, using the
Ziegler-Nichols
method, calculates and tunes parameters P, I and D of the controller loop. Additional
parameters (fuzzy logic,
Inertia
, output limits,
Dead zone
) are not in this mode configurable
and the user must select them for his own applications. The Autotuning process is described
later in this chapter.
