I am trying to control a robot using an ordinary differential equation that cannot be solved numerically with Euler or Runge Kutta methods. I've found that only stiff solvers like LSODA and BDF effectively integrate the system. I found a C++ implementation of LSODA but it depends on libraries that Arduino does not have access to. Does anyone know of any implementations of stiff solvers for Arduino? Thanks!
What does that mean? Open source C and C++ code libraries are available to handle just about any common math problem.
Depends on which "Arduino" - probably not a chance on an UNO.
What robot control technique requires solving stiff ODEs? That seems totally impractical, especially using microprocessors.
If you really want to continue the project with Arduino, consider reformulating the problem, or the control model.
