Time-Domain Simulations in Control System Designer App
When performing optimization-based tuning in the Control System Designer (Control System Toolbox) app, Simulink® Design Optimization™ software automatically sets the model simulation start and stop times; you cannot directly change them. By default, the simulation starts at 0 and continues until the app determines that the dynamics of the model have settled out. In addition, when the design requirements extend beyond this point, the simulation continues to the extent of the design requirements. Although you cannot directly adjust the start or stop time of the simulation, you can adjust the design requirements to extend further in time and thus force the simulation to continue to a certain point.
