Abstract:	The optimal hybrid tracking control problem for analog neutral systems with multiple discrete and distributed time delays is discussed in this paper. In order to obtain good tracking performance and improve the drawback of conventional optimal control in selecting the weighting matrices, the observer with evolutionary-programming (EP)-based alternative digital redesign control technique is presented to find a low-gain digital tracker for hybrid control of the analog neutral system. A novel approach that combining the EP method and the high-gain property is proposed to search the optimal weighting matrices in the performance index to achieve the "best" tracking control for analog neutral systems for the first time. Finally, a numerical example is given to illustrate the proposed methods.
