The invention discloses a double-winding three-phase motor double-control four-drive type controller and a control method for controlling a double-winding three-phase motor by applying the controller.The double-winding three-phase motor double-control four-drive controller comprises two single-chip microcomputers, two sets of power supply systems capable of providing power independently, and fourthree-phase drive circuits which are the same in structure and operate independently. In terms of control, each single-chip microcomputer can control the motor through one three-phase drive circuit.According to the invention, a control mode that two single-chip microcomputers carry out single control or double control on the double-winding three-phase motor and two three-phase driving circuits corresponding to one single-chip microcomputer carry out full control or half control on the double-winding three-phase motor is realized. According to the invention, if one of the two single-chip microcomputers is damaged or one or more of the four three-phase driving circuits are damaged, the motor can still operate normally. Compared with the prior art, the application of the control system hasthe advantage that the control stability of the motor is greatly improved.
一种双绕组三相电机双控四驱式控制器以及应用该控制器进行对双绕组三相电机进行控制的控制方法。该双绕组三相电机双控四驱式控制器包括两个单片机、两套能够独立供电的电源系统、四个结构相同且独立运行的三相驱动电路。就控制方面而言,每一个单片机都能够通过一个三相驱动电路对电机进行控制。本发明实现了“由两个单片机对双绕组三相电机进行单控或双控;由一个单片机所对应的两个三相驱动电路对双绕组三相电机进行全控或半控”的控制方式。本发明中,如果两个单片机中的一个损坏,或者四个三相驱动电路中的一个或者多个发生损坏,电机仍能够正常运行。相比于传统技术而言,本发明控制系统的应用对于电机的控制稳定而言,具有大幅提升。
