Unified model of voltage/current mode control to predict saddle-node bifurcation (1202.4533v1)
Published 21 Feb 2012 in cs.SY, math.DS, and nlin.CD
Abstract: A unified model of voltage mode control (VMC) and current mode control (CMC) is proposed to predict the saddle-node bifurcation (SNB). Exact SNB boundary conditions are derived, and can be further simplified in various forms for design purpose. Many approaches, including steady-state, sampled-data, average, harmonic balance, and loop gain analyses are applied to predict SNB. Each approach has its own merits and complement the other approaches.
