| Permanent Magnet Synchronous Machine(PMSM) has been paid more attention in the past two decades by researcher in the motor and control system fields because of its excellent performance for example small cubage, great power density and good efficiency We can foresee the further development about PMSM and its control system with the reduce of the permanent magnet material's price and producing the rotor progress in the power electronics apparatus and high-speed processor and control theories.. PMSM may take the place of common power excitation motor and control system in many fields.With the development of PMSM design and its control techniques, PMSM has been widely used in many industrial applications. Having a comprehensive understand aim at PMSM and control system's development, actuality, and tendency, we bring forward two methods about how to control PMSM system: Direct Torque Control (DTC) and Vector Control. There are advanced strategy.They will be discussed in this thesis.The main contents of the study include: PMSM operational principle, the basic idea of PMSM DTC,the basic idea of PMSM Vector Control ,t A set of PMSM strategy and the simulation platform are presented; the simulation result proves that this set of strategy is effective based on the two strategy.; In the last we developed, and successfully implemented the hardware and software design of PMSM based on DSP. |
