Control system engineers use MATLAB® and Simulink® at all
stages of development – from plant modeling to designing and
tuning control algorithms and supervisory logic, all the way to
deployment with automatic code generation and system
verification, validation, and test. MATLAB and Simulink offer:
Model-Based Design for Embedded Control SystemsDOWNLOAD
Use MATLAB and Simulink to build accurate plant models. Describe the complex dynamics of your plant using a variety of supported modeling approaches, and use the most appropriate approach for each component in your plant to create the system-level plant model.
Estimate plant dynamics from input-output data using system identification when you do not know the detailed structure of the model. Alternatively, create complex multidomain plant models without having to derive the underlying first-principles equations using physical modeling tools. Use blocks that represent mechanical, electrical, magnetic, hydraulic, pneumatic, and thermal components to map the component topography and physical connections of your system.
Analyze and develop closed-loop compensators, and assess key performance parameters, such as overshoot, rise time, and stability margins. Trim and linearize nonlinear Simulink models. You can also model and analyze the effects of uncertainty on the performance and stability of your models.
Take advantage of Bode plots, root locus, and other linear control design techniques and automatically tune PID controllers in a simulation model or on test hardware. Prebuilt tools let you automatically tune decentralized multivariable controllers and leverage advanced control strategies, such as model predictive control and robust control. Use optimization methods to compute controller gains to meet rise-time and overshoot constraints.
Use Stateflow® to model, design, and simulate the supervisory logic in your control system, which schedules the operation of the controller, controls the operational mode of the system, and performs fault detection, isolation, and recovery (FDIR).
Use the graphical editor to build your logic as a state machine or a flow chart. You can also combine graphical and tabular representations, including state transition diagrams, flow charts, state transition tables, and truth tables, to model how your system reacts to events, time-based conditions, and external input signals. Visualize system behavior during simulation by using state diagram animations to highlight the active states and transitions in your model.
Once you have designed your control system algorithms, you can refine them for implementation. You can specify the fixed-point data type properties of your design to prepare it for implementation with fixed-point arithmetic. After verifying control algorithms in closed-loop desktop simulations, deploy them to production microcontrollers, PLCs, and FPGAs by automatically generating C, structured text, or HDL code.
You can continuously test and verify your control system. Conduct hardware-in-the-loop (HIL) testing by running the control algorithm on an embedded controller and running the plant model in real time on a target computer connected to the controller. You can further verify and test your control system using formal verification methods.
