Abstract�� Voice coil motor (VCM) direct drive valve (DDV) is a type servo valve which utilize the VCM drive spool directly and its dynamic characteristic is depends on the performance of VCM. Unfortunately, some of design parameters of VCM are contradictory when ambition the best performance, it always need to trial-and-error many times by designer. Based on the introduction of principle and structure of VCM, the effect of each design parameters for the performance was analyzed, and the parameters need to be optimized synthesized was pointed out. The optimization objective function was defined under the design constraint, and the improved particle swarm optimization (PSO) methods which use inertia weight and constriction coefficient were applied for search the optimum parameters in multidimensional parameters space. The best parameters were obtained under design constraint. It also improve that PSO is an efficient way to solution these questions.
