Abstract

This paper investigates the computation complexity and long resolving time problems that exist in the optimal control algorithm based on MLD (Mixed Logical Dynamical) model. Basing on polynomial matrix, an improved algorithm is presented to reduce the dimension of the inequality constraints in MLD model. The computation complexity in the optimal algorithm has been reduced greatly. The resolving time has been also reduced. Thus computation efficiency is achieved. A piecewise linear switching system is used demonstrate proposed algorithm. Simulation results show the promising performance of the improved algorithm.
