Fast development of controllers with Simulink Coder

The aim of this paper is to describe rapid design and realization of a embedded controllers by using MATLAB toolboxes like Simulink Coder. The Simulink Coder generates and executes C and C++ code from Simulink diagrams, Stateflow charts, and MATLAB functions. An automatic code generation enables implementation of Simulink controller models directly to the PLC without manual coding. The generated source code it is possible to use for real-time and non-real-time applications, including rapid prototyping and hardware-in-the-loop testing. The code can be tuned and monitored using Simulink or run and interact with the code outside MATLAB and Simulink. The integration of I/O cards in the model enables the simulation of data acquisition, so that control system can be performed directly from Simulink. The controls deployed to the real-time target can be used for communication with Simulink using the external mode, and also can provide data exchange of process variables and block parameters to other applications on the PLC system (IEC 61131, C, C++, Java). The controllers' implementation was tested with climate unit laboratory model and predictive controllers and decentralized PID controllers were used.
