PMSM-control
永磁同步电动机调速系统由pmsm月吸逆变器、永磁同步电动机和机械负载三部分组成,每个部分都具有非线性特性和参数的不确定性。因为PWM逆变器死区的存在,在低速以及调制频率很高时,死区特性将会导致逆变器输出电压包含很大的谐波分量,使得电机转矩发生很大的
脉动,甚至导致系统的不稳定。有些学者采用变结构控制降低死区的影响,由于变结构控制本身具有抖振现象,这使得所设计的控制器在到达滑模平面之前很容易激起系统的未建模动态,导致系统无法克服逆变器死区的影响。

说明: 采用Laser - PVDF 实验系统对纳米AlP/ SiO2 中激光超声信号进行采集. 利用小波的多尺度分解、重
构和消噪功能,提取出直达波及其反射回波,测量了时间间隔和纳米AlP/ SiO2 的纵波声速. 结果证明小波变换
的方法能有效地处理复杂激光超声信号.(Using Laser- PVDF experimental system of nano-AlP/SiO2 Laser ultrasonic signal acquisition. Using wavelet multiscale decomposition, reconstruction and de-noising function, extracted from direct wave and its reflection echo measured time interval and nano-AlP/SiO2 of the longitudinal wave speed of sound. wavelet transform results show that the method can effectively deal with the complexity of laser ultrasonic signals.)
