%X Usually, an optimal preview servo system uses the same quadratic performance index as the original optimal servo system. The design idea is to further minimize performance index. If the known system was not designed with optimal control method, people would use a performance function dependent only on the feedforward terms to design the so-called optimal FF compensating system. Usually, these two kinds of systems are handled separately. In this paper, we present a method to deal with them at the same time such that the known optimal preview servo system and optimal FF compensating system are all special cases. Computer simulation is given at the end of this paper to compare this method with optimal servo system and optimal preview servo system.
