| 摘 要： | 提出了三相感应电机新的逆变驱动策略与电流模式定向控制(Current Mode Oriented Control,简称CMOC)的方法.在新逆变驱动策略的控制下,三相感应电机具有平滑的控制输入和更高的控制精度.完整的控制系统由内部控制环与外部控制环组成,内环实现感应电机速度调节和电流控制,而外环实现电机驱动.由于新逆变驱动策略具有LC滤波,因此感应电机的控制输入平滑.逆变器开关驱动由滑模控制实现.由于逆变器开关律由滑模控制直接驱动,因此不存在PWM驱动方式下的死因时间问题.实验结果验证了该方案的有效性.

| Abstract: | The accuracy of the new inverting drive is rather high due to the control inputs of three-phase induction motor are perfectly smoothed.The whole control system is made up of cascaded control loops,the inner control loops for speed regulation and currents control of induction motor,and outer control loops for motor drive.With the new inverting drive strategy by LC filter,the control inputs of induction motor are smooth.The inverter's switching drive is realized through sliding mode control.Because inverter's... |
