Application #6: Autotuning in practice

One of the examples of the practical application of a controller with auto-tuning is the process of controlling the elements annealing furnace.

The temperature set point is shown in the form of an appropriate time profile. It usually consists of three stages: heating, annealing, which means maintaining at a constant temperature and cooling. The regulation is based on the PID controller whose parameters are selected automatically during autotuning process.

The following model works well in the application: CMC-141-PS42/E/UN3/S8/E-0B1

Signal inputs:

The UN3 module consists of 3 isolated universal inputs (U/I/RTD/TC/mV). In this case, the temperature input is used. It reads off the temperature measured inside the furnace.

Signal outputs:

The S8 module consists of 8 SSR outputs, one of which is used to control heating in the furnace. Another ones can set the cooling fans in operation, depending on the nature of the process.

Communication:

The USB module allows you to download data saved during the recording of the entire process.

Configuration:

The user can create up to 8 time profiles, i.e 8 "heating programs" customized to the requirements of individual elements. Before starting the process, the appropriate profile is selected.

Special features:

The USB port, for the convenience of use, is placed on the front of the device.
