Design of embedded virtual dynamical signal analyzer
In order to provide a design tool for the photoelectronic tracking systems in remote controls,an embedded virtual dynamical signal analyzer is established,and its applied algorithms such as system identification are investigated. Based on the platform of a photoelectronic tracking system and combining the concept of a virtual device with the embedded technology,an idea for an Embedded Virtual Dynamical Signal Analyzer(EVDSA) is presented and the system infrastructure is established. Three layers of softwares for the system infrastructure is designed respectively and the application layer based on the system identification technology is introduced especielly. The current loop and the speed loop of the photoelectronic tracking system are tested by the EVDSA and the experimental results show that the photoelectronic tracking system meets the design demands for the bandwidths of a current loop of 266.05 Hz and a speed loop of 20.3 Hz.The virtual device has good accuracy and practicability,which can satisfy the design tool requirements of precise,convenient and rapid speed design levels and can improve the efficiency of the photoelectronic tracking system.
