The design of controllers for synchronizing motions of two axes systems is considered. Two robust control approaches to achieve the synchronization objective as well as the regulation objective are developed. In robust control scheme, synchronization is treated as an extra constraint rather than a stability requirement. Simulations show that during transient stage, the synchronization control algorithm performs a faster convergent rate on synchronization error while without synchronization control, this error will not converge until steady state are reached. The paper considers the linear quadratic design method from the view point of synchronization also. It is shown that, for XY table motion control, large weighting on the synchronization term in the quadratic performance index significantly reduces the resulting contouring error.
