The permanent magnet synchronous motor is decoupled into second-order linear speed subsystem and first-order linear flux subsystem. The aim space voltage vector is ascertained by combining sector judgment of stator flux with the practical system inputs after linearization and decoupling. The system is decoupled into two linear subsystems, flux and rotor speed, which realizes the completely dynamic decoupling for permanent magnet synchronous motor speed control system.
