Simulink is a visual simulation tool in MATLAB, a block diagram design environment based on MATLAB, and a software package for modeling, simulation and analysis of dynamic systems, which is widely used in modeling and simulation of linear systems, nonlinear systems, digital control and digital signal processing. Simulink can be modeled by continuous sampling time, discrete sampling time or two mixed sampling times, and it also supports multi-rate systems, that is, different parts of the system have different sampling rates. In order to create a dynamic system model, Simulink provides a graphical user interface (GUI) to create a model block diagram. This creation process can be completed by clicking and dragging the mouse, which provides a faster and more direct way for users to see the simulation results of the system immediately.
Simulink is a multi-domain simulation and model-based design tool for dynamic systems and embedded systems. For various time-varying systems, including communication, control, signal processing, video processing and image processing systems, Simulink provides an interactive graphical environment and a customizable module library to design, simulate, execute and test them. .
Other products based on Simulink extend the multi-domain modeling function of Simulink, and also provide corresponding tools for designing, executing, verifying and confirming tasks. Simulink is closely integrated with MATLAB, which can directly access a large number of tools of MATLAB for algorithm development, simulation analysis and visualization, batch script creation, modeling environment customization and signal parameters and test data definition.
