Design And Implementation Of One Gun Servo System Based On DSP

With the development of science and technology, microelectronics technology and computer network communication technology has been used in all kinds of control system. The contents of this paper is to design the software and hardware of one antiaircraft gun servo system. According to the examination of the present situations of the modern antiaircraft gun servo system, and the analysis of the practical prospect of Digital Signal Processor(DSP) in the modern antiaircraft gun servo system, The micro control chip DSP TMS320F2812 as the main controller to construct digital artillery with the hardware design of the pneumatic control system, using ISO1050 chip as the CAN level conversion, photoelectric isolation and transceiver unit, using AD5752 chip as digital to analog conversion module, then choose CPLD chip as a temporal integration, address decoder, encoder, data conversion the switch signal acquisition and integrated logic control. At the end of the DSP chip interface to edit, compile environment is introduced and a brief discussion about the study on control algorithm of servo system.analyses the application of DSP control module, CPLD and CAN communication module in servo system, also, this paper analyses the programming environment of DSP and the control algorithm of servo system.So far, this project has been completed and tested.The following works have been done according to the requirement of the project:1) Introduced the concept,the function,the components of digital servo system and communication system.2) Accomplished device selection and DSP-based hardware design.3) Introduced the application of the DSP control module and the CAN,RS485 communication module in this system.4) Discussed appropriate control algorithm of servo system.5) Accomplished the debugging of the software hardware and system demand.
