Model Predictive Control Toolbox™ software provides code generation functionality for controllers designed in Simulink® and MATLAB®.
After designing a controller in Simulink using any of the MPC blocks, you can generate code and deploy it for real-time control. You can deploy controllers to all targets supported by the following products:
Simulink PLC Coder™
The sampling rate that a controller can achieve in real-time environment is system-dependent. For example, for a typical small MIMO control application running on Simulink Real-Time, the sampling rate can go as low as 1–10 ms. To determine the sampling rate, first test a less aggressive controller whose sampling rate produces acceptable performance on the target. Next, increase the sampling rate and monitor the execution time used by the controller. You can further decrease the sampling rate as long as the optimization safely completes within each sampling period under the normal plant operations. To reduce the sampling rate, you can also consider using explicit MPC. However, explicit MPC controllers have a larger memory footprint, since they store precomputed control laws.
You can generate code for any of the Model Predictive Control Toolbox Simulink blocks:
