Abstract


Electro-hydraulic proportional control technology is nearly 30 years of rapid development , proportional flow internal proportional solenoid valve action, according to the input voltage signal and the spool displacement so as to change the valve orifice area , the flow rate output proportional to the control voltage . Proportional controller is electric -hydraulic proportional technology main research directions , is used to provide the performance characteristics of current proportional solenoid and proportional flow valve is open or closed loop regulation of electronic devices . At present, whether analog or digital proportional controller price is very expensive, and the lack of flexibility in terms of data processing and analog proportional amplifier . For the status quo , and extensive research on the functions and features of the domestic and foreign proportional controller design a the LPC2290 processor - based high-performance and high reliability digital proportional controller . Firstly, the structure and characteristics of the proportional flow control valve , and then to LPC2290 microprocessor as the core , extends the PWM power amplifier circuit , the valve position measurement amplification circuit , the regulated power supply circuit , A / D and D / A conversion circuit , UART serial communication circuit and CAN interface circuitry . The power amplifier circuit using PWM anti unloading Dutch power amplifier stage drive proportional solenoid improve the dynamic response characteristics of the proportional solenoid . The article uses the the Multisim software focuses on the design of the power supply module , PWM power amplification module and valve position measurement amplifier module simulation study , the results show that the design of the circuit meets the design requirements . The digital proportional amplifier software is based on the real - time operating system designed μc/OS- Ⅱ . The software is divided into data acquisition and filtering module , A / D converter module , serial communication module and CAN bus communication module . This article gives the mission requirements and the design of several modules flowchart for the detailed preparation of the follow-up software .
