Stability analysis of a tightly controlled load supplied by a DC-DC boost converter with a modified sliding mode controller

Abstract

It is common in transportation systems to have small LC filters connected to constant power loads. That may lead to instabilities. To stabilize the system without increasing its weight and volume, a new control scheme is studied, based on a sliding mode controller. It is applied to a DC-DC boost converter that supplies a constant power load. The stability analysis is done using discrete-time model to obtain a Jacobian matrix. Eigenvalues of the Jacobian matrix are calculated to conclude about the stability. Simulations and experimental results are given to validate the modified control.
