Abstract: A Dual control algorithm of Generalized Predictive Adaptive Control（DGPAC） is presented，it considers errors of estimated parameters sufficiently in the process of identifying model，accumulates the information of estimated parameters maximal at the same time of system states optimum moving along the scheduled track so as to quickly reduce uncertainties.The simulation results show that this control algorithm is more effective than common generalized predictive adaptive control.
