Abstract：Combined with fuzzy control, neural network control and genetic algorithm, a compound control strategy was proposed to solve the unsafe and unsteady operation due to out-of-step for a vertical-moved and discontinuous stator winding a permanent magnet linear synchronous motor (PMLSM) .The structure and working principle of this control model are introduced, the design and parameter optimization method of the fuzzy neural network are presented.It is shown that the proposed control strategy is effective for enhancing the stability and safety of the vertical-moved discontinuous stator winding a permanent magnet linear motor and a drive system
