| Abstract: | Control system of the dual DSP controller module was introduced with a data interface of USB2.0.The paper focused on the architecture of the control system,the protocol of data transfer,the inner architecture of interface device,and the real-time data exchange and control between the host and the dual DSP through USB2.0 interface.A miniaturized and modularized control system with high performance was developed,in which there were dual DSP,one DSP interfaced to digital data collecting path,and the other interfaced to analog data collecting path.The USB interface could control all the behavior of the dual DSP.This system was applied in a compound axis control photoelectric track system successfully.Besides,the principle of compound axis control method was also introduced and the implementation plans of main axis and sub axis control loop were given.The test result verified the superiority of such architecture. |
