| 目的 保证永磁同步电机在变速变载时能够快速响应的同时，降低其在稳态时的转矩脉动和开关频率，使永磁同步电机在整个包装过程更加高效节能。方法 分析永磁同步电机的2种控制策略DTC和PIPC的优缺点和共同点，提出在启动、变速和变载过程采用DTC控制策略保证电机的动态响应速度，在稳态时切换到PIPC控制策略，降低电机的转矩脉动和开关损耗。结果 仿真结果表明，2种控制策略能够实现平滑切换，电机动态响应快，抗干扰能力强，稳态时转矩脉动小、开关频率低;相比DTC，在空载、轻载和重载时转矩脉动分别减小了30%，12.5%和2.4%，开关频率降低了约45%;相比PIPC，响应速度提高了约7%。结论 相比单一的控制策略，DTC_PIPC混合控制算法融合了2种控制策略的优点，使电机在整个运行过程既能快速应对各种突变情况，又能降低其在稳态运行时的转矩脉动和开关频率。 |

| The work aims to ensure that the PMSM can respond quickly when changing speed and load, and at the same time reduce its torque ripple and switching frequency in steady state, so as to make the permanent magnet synchronous motor more efficient and energy-saving in the packaging process. The advantages, disadvantages and common points of DTC and PIPC of PMSM were analyzed. The DTC control strategy was adopted to ensure the response speed of PMSM in the process of starting, changing speed and changing load, and then switch to PIPC control strategy in the steady state to reduce the torque ripple and power loss of PMSM. The simulation results showed that the two control strategies could achieve smooth switching, and the motor had fast dynamic response speed, strong anti-interference ability, small torque ripple in steady state and low switching frequency. Compared with DTC, in no load, light load and heavy load, the torque ripple was reduced by 30%, 12.5% and 2.4%, the switching frequency was reduced by about 45%; compared with PIPC, the response speed was improved by about 7%. Compared with single control strategy, hybrid control algorithm DTC_ PIPC combines the advantages of the two control strategies, so that the motor can respond to all kinds of sudden changes quickly in the whole motion process, and reduce its torque ripple and switching frequency in the steady-state operation. |
