Design of the System Controller for High-power PMSM Used in Aviation Hydraulic Pumps

To meet the high requirements for functionality, performance, and reliability of the drive system in high-power aviation hydraulic electric pumps, a high-power hydraulic electric pump system controller is proposed based on a DSP+FPGA architecture. The main control circuit of the controller adopts a DSP+FPGA architecture design to satisfy the requirements for high-speed acquisition of multiple control signals and high-speed computation. The control strategy employs Field-Oriented Control （FOC） based on Maximum Torque Per Ampere （MTPA） to meet the demands for high performance and high efficiency in the motion control of Interior Permanent Magnet Synchronous Motors （IPMSMs）. Experimental results demonstrate that the system controller can reliably drive a 100kW permanent magnet synchronous motor under a 540V voltage level, with an efficiency of over 95%.
