The Research And Development Of Hydraulic Servo Controller Based On The DSP And FPGA

Hydraulic servo control system is a kind of common automatic control system，whichhas been widely used in many areas.With the help of Motion controller, integrateddesign of hydraulic servo controller and hydraulic servo drive formed the design andresearch of hydraulic servo motion controller.It has been one of the hotspots oftechnical research.In view of the hydraulic servo motion controller.The article carriedout related design and research work.Based on the analysis of hydraulic servo system characteristic, and FPGA andDSP as the core, hydraulic servo motion controller was designed.Motion controlsystem,especially high speed and high precision motion control system, is verydemanding to the requirements of the servo cycle,but servo cycles of Ms level are notfar enough for the control requirements.DSP chip has high-speed data processingability, which can help to improve the rapid response and control precision of thesystem;The FPGA technology application can integrate IO management interface ofcomplex axis motion controller effectively,simplify system design,and enhance systemperformance.At the same time, Profibus-DP industrial field bus interface and RS232/RS485serial communication interface are embedded in the system.Abundantinformation Internet interface can help hydraulic servo motion controller embed intothe complex industrial control system. Using LCD touch screen as support,man-machine interface design was completed well;On the basic of hardware platform ofdesign,system software design and control algorithm research work are completed;Inthis article,Through the simulation tests and lab online test, design of hydraulic servomotion controller proved the scheme feasibility,and obtained satisfactory control effect.
