The invention discloses a multi-space optimization control method for an asymmetric open-winding multi-phase permanent magnet synchronous linear motor. The method comprises the following steps of S1, collecting six-phase input voltage and six-phase input current when the motor runs and position information and moving speed of the six-phase permanent magnet synchronous linear motor; s2, acquiring a flux linkage amplitude observed value, a flux linkage phase observed value, a thrust observed value and a d-axis current of a decoupling static space through the six-phase input voltage and the six-phase input current; s3, feeding the flux linkage amplitude observation value, the flux linkage phase observation value, the thrust observation value, the d-axis current and the moving speed into a motor control double closed loop together to perform direct thrust control on the six-phase permanent magnet synchronous linear motor; and S4, taking a thrust demand signal output by a thrust hysteresis controller ...
