Investigated Scenarios with PID Controllers and FMUs
Explore various cases and scenarios involving PID controllers and Functional Mockup Units (FMUs) in a comparison between LS-DYNA and Scilab models. Investigate the effects of different PID controller parameters on the system's behavior, utilizing mass-spring-damper setups and 2D coordinate systems. Understand the implications of PID controller tuning on system performance and response.
