Prototyping of new controls in running plants is challenging as it may impact operation. Usually, the plant's architecture, programming tools, and development methods do not allow efficient experimentation with new technologies. Engineers adopt the Simulink Real-Time testing workflow to take advantage of Simulink capabilities for modeling, tuning, and optimizing model-based control designs running in real-time on Speedgoat hardware.
Connect to the plant controller by adding the target machine to the existing industrial network (PROFINET, EtherCAT, …) or using other Ethernet-based protocols such as Real-time UDP and Modbus TCP to interface the PLC directly. The so-called bypass controller is then prepared to receive actual data from the plant. The real-time application calculates additional control values that the PLC sends to the related controlled system, such as the cutting system of a newspaper printing machine or the deicing unit of a wind turbine.
The System Identification ToolboxTM provides techniques that help identify continuous-time and discrete-time transfer functions of the controlled system. The ability to predict the system response makes it easy to develop an initial control design quickly.
