Analysis tools

(Currently available only in the PLECS Blockset.)

In addition to the standard transient simulation PLECS features a set of advanced and easy to use analysis tools.

Steady-state analysis

The steady-state analysis enables you to determine the periodic steady-state operating point of a switching system without having to simulate the startup transients. This is particularly useful in combination with thermal simulations where the time-constants can easily span 6 orders of magnitude (with the switching period at the bottom and the thermal spreading at the top of the scale).

Small-signal analysis

Transfer functions play an important role in controller design. PLECS enables you to determine open-loop transfer functions or closed-loop gains of switching systems without having to revert to averaged models.

Calculation of state-space matrices

PLECS gives you access to the state-space matrices that describe a system. You can use these matrices for your own advanced analyses, e.g. eigenvalue analysis or state-space averaging.
