| 摘 要： | 为了更好地解决无位置传感器PMSM(Permanent Magnet Synchronous Motor)的驱动问题,通过对永磁同步电机数学模型的分析,利用较易测量的电流、电压值推导了转角的数值计算公式,并将转速和转角估算模块加入到矢量控制系统及直接转矩控制系统中,用估算的转速转角直接作为反馈量，构成相应的系统并进行仿真。对模型参考自适应控制策略结合永磁同步电机数学模型进行了推导,得出转速转角估算模块并将其加入到直接转矩控制系统中。仿真结果表明,矢量控制的转速较稳定,直接转矩控制转速波动较大但转速响应较快,抗干扰能力较强。

| Abstract: | When sensorless control system is applied in vector control and direct torque control system the responses are different for the different characters of the vector control system and direct torque control system.We analyze mathematic models of PMSM(Permanent Magnet Synchronous Motor) and the results of rotor angle are generalized by the voltage and current which were meatured by sensors,the simulation results of vector control system and direct torque control system without position sensor are provided.The ... |
