Abstract: The doubly salient motor has a sturdy structure and is used for aviation starting generators , significantly reducing system maintenance work. In response to the high starting torque of aviation engines , a doubly salient motor drive control system based on DSP and CPLD architecture is proposed. Based on the structural characteristics of DSP and CPLD and the functional requirements of drive control , a modular design method is
adopted to divide and study the functions that DSP and CPLD each need to undertake. Among them, DSP mainly completes the closed-loop control algorithm and starting current control of the motor, while CPLD mainly completes the generation of motor switch signal signals and speed measurement , as well as the generation of 12 phase drive signals. The simulation and experimental results show that the drive control system can reliably and efficiently complete the control of the motor, achieve torque ripple suppression and current control of the doubly salient motor,
and achieve smooth starting of the aircraft engine.
