SUMMARY

The discussion focuses on solving a 2 degrees of freedom (d.o.f.) spring-mass-damper system using state-space representation. The user has formulated the system's matrices but struggles with integrating the equations due to an imbalance in the number of variables and equations. A key insight provided is the inclusion of additional equations derived from the derivatives of the state variables, specifically w1 = y1' and w2 = y2'. This approach is essential for achieving a solvable system.

PREREQUISITES
  • Understanding of state-space representation in control systems
  • Familiarity with spring-mass-damper dynamics
  • Knowledge of differential equations and their integration
  • Basic concepts of linear algebra, particularly matrix operations
NEXT STEPS
  • Research methods for solving state-space equations in control systems
  • Learn about the use of MATLAB for simulating spring-mass-damper systems
  • Explore numerical integration techniques for differential equations
  • Study the implications of additional state equations in multi-variable systems
USEFUL FOR

Engineers, control system designers, and students studying dynamics and control theory will benefit from this discussion, particularly those working with multi-variable spring-mass-damper systems.

I've got all the matrices in state-space form, but how do I solve them? I tried integrating the equations one by one, but it seems like I end up with more variables than equations.

Thanks for any help, I'm completely lost.

Posting the equations of your problem would help. In case it helps, remember that you have 2 extra equations from w1=y1', w2=y2' :smile:
