英文摘要：

A drive control platform based on digital signal processor （DSP） and field programmable gate array （FPGA） is designed to meet the need of multi motors speed servo system and to make up the shortages of the existing drive controllers. A floating point DSP was used as primary controller to perform the functions such as computing control algorithm, receiving control instructions and synchronizing mo tor speed. A lowcost FPGA was used as secondary controller to achieve the functions such as dualport RAM, PWM generation, A/D sampling control and speed acquisition. Programming design of DSP and functional design of FPGA were accomplished using top down mod ularized method. Two brushless DC motors （BLDCM） were used to test the control function of the drive control platform. The simulation and experiment results verify the validity of the control platform. And the proposed control platform has simple structure and excellent ex pandabilitv.
