Matlab/Simulink is very powerful and flexible software for technical computing, which includes modeling, simulating, analyzing dynamic system , etc. Simulink provides a graphical user interface (GUI) for building models as block diagram by click-and-drag mouse operation. And Real-Time Workshop based on Matlab/Simulink supplies a real-time development environment—an approach from system design to hardware implementation. You can shorten development cycles and reduces costs with real-time workshop by testing design iteration on target hardware. Matlab embedded controller , which is based on real-time workshop and real-time workshop embedded coder, presents a real-time embedded control solution for I-8438-G/8838-G equipped with various I/O modules. There are more than 20 I/O-bridge and system-level Simulink function blocksets built for customized application. By using Simulink development environment and Matlab Embedded Controller blocksets, control algorithms can be easily and quickly developed and verified. As soon as the algorithm has been confirmed, by pressing a build button, users can convert the control model to executable code, and download it to the controller for test and practical application via RS232 and Ethernet interface without any hand coding process. Therefore, engineers and researchers can put more focus on algorithm design and development in order to obtain a high performance control system.
