We present a novel formulation, called the WaMPDE, for solving systems with
forced autonomous components. An important feature of the WaMPDE is its
ability to capture frequency modulation (FM) in a natural and compact manner.
This is made possible by a key new concept: that of warped time, related
to normal time through separate time scales. Using warped time, we obtain a
completely general formulation that captures complex dynamics in autonomous
nonlinear systems of arbitrary size or complexity. We present computationally
efficient numerical methods for solving large practical problems using the
WaMPDE. Our approach explicitly calculates a time-varying local frequency
that matches intuitive expectations. Applications to voltage-controlled oscillators
demonstrate speedups of two orders of magnitude.
