Abstract

A new algorithm based on projection techniques is proposed for constructing parameterized reduced order systems of nonlinear equations. The resulting reduced system can be used to trace the variation in the steady-state solution in response to variations in any arbitrary circuit or physical parameter. Experimental results show up to two orders-of-magnitude reduction in the problem size required in conventional harmonic balance technique.
