Abstract :
Accelerated convergence to the steady-state solution of closed-loop regulated switching-mode systems is achieved by more accurately computing the sensitivity matrices involved through a new matrix-based algorithm. By taking into consideration the variation of the timing of the intracycle intervals of a switching-mode system with respect to changes in the state vector, the new algorithm is able to predict system sensitivity with considerably greater accuracy but only slight penalty in computation time over existing algorithms. Newton-Raphson iteration is then applied to compute the steady state, substantially speeding up convergence to the solution as compared to brute-force simulation methods.
