Reduced Order Modelling of Inverter Chain Circuit using Nonlinearity Aware TPWL

摘要

Model order reduction techniques are often used to reduce the order of large order systems so that they get easy to simulate and control. Trajectory piecewise linear is a model order reduction technique that is used to reduce the order of nonlinear systems. Nonlinearity aware trajectory piecewise linear approximation is a modification of trajectory piecewise linear method that uses dynamically inspired weight assignment. Such weight assignment scheme makes the approximation more sensitive to the nonlinearities involved. This paper uses the nonlinearity aware trajectory piecewise linear approximation to reduce the order of chain of inverter circuit that forms a large order nonlinear system.
