PIETOOLS 2025 provides several improvements, including more accurate and sophisticated stability tests, the ability to define PIEs with infinite-dimensional inputs and outputs, features for robust analysis and control, along with enhanced 2D functionality.

Major Updates:

  1. Several new notions of PDE stability have been defined and implemented. The default stability test is now PIE to PDE stability, which is the weakest of these notions.
    • Scripts now exist to test Lyapunov and exponential in both the PIE to PDE, PDE to PDE sense.
  2. PIE and PDE objects can now have infinite-dimensional inputs and outputs.
    • L2-gain analysis routines now support infinite-dimensional inputs and outputs.
  3. A test for well-posedness of univariate PDEs has been included and conversion scripts updated.
  4. PIESIM allows for simulation of 2D PDEs

Minor Updates:

  1. The ability to utilize second order time derivatives in the command line interface has been modified.
  2. Updated lpigetdegrees
