【摘要】：隨著制造業(yè)的發(fā)展，特別是航空航天技術(shù)的飛速發(fā)展，我國(guó)迫切需求高精度、高效率、和高性能的大噸位多缸液壓機(jī)。本課題針對(duì)多缸液壓機(jī)，，利用最新的電子信息技術(shù)，完成了基于以太網(wǎng)通訊的多缸液壓機(jī)高速數(shù)字伺服控制器的開(kāi)發(fā)與設(shè)計(jì)。 首先簡(jiǎn)單介紹了多缸液壓機(jī)及伺服控制系統(tǒng)的發(fā)展和數(shù)字伺服控制系統(tǒng)的發(fā)展和組成。然后根據(jù)多方比較和綜合考慮，給出了多缸液壓機(jī)伺服控制系統(tǒng)的需求分析，并根據(jù)算法需求、工程實(shí)際和對(duì)比國(guó)外已有的多軸伺服控制器，提出基于DSP（TMS320F2812）+FPGA（EP2C8Q208）的多缸液壓數(shù)字伺服控制器的設(shè)計(jì)方案。使用高速數(shù)字信號(hào)處理器-DSP作為控制器的中央處理芯片，來(lái)運(yùn)行控制算法和底層協(xié)議，提高了控制器的運(yùn)行速度，減小了控制周期。使用FPGA作為控制器的數(shù)據(jù)預(yù)處理單元，來(lái)完成DSP與外部模塊的信息交換與預(yù)處理，使所有的讀寫邏輯都由硬件完成，特別是將測(cè)速模塊在FPGA內(nèi)以硬件的形式實(shí)現(xiàn)，這樣在提高了控制器的實(shí)時(shí)性的同時(shí)還加大了系統(tǒng)的靈活性。為了使伺服控制器能與其他設(shè)備進(jìn)行信息交換，還加入了以太網(wǎng)通信接口，使得控制器可以開(kāi)放地接入網(wǎng)絡(luò)與上位計(jì)算機(jī)進(jìn)行網(wǎng)絡(luò)通訊。 其次，根據(jù)所提出的設(shè)計(jì)方案，課題完成了多缸液壓機(jī)伺服控制器的設(shè)計(jì)與實(shí)現(xiàn)。為了完成DSP與外部功能模塊直接的信息交互和數(shù)據(jù)處理，利用QuartusⅡ軟件對(duì)FPGA進(jìn)行內(nèi)部邏輯功能編程、仿真和驗(yàn)證。使DSP可通過(guò)其自帶的外部存儲(chǔ)器端口（16位并行總線）對(duì)各個(gè)外部模塊進(jìn)行控制與數(shù)據(jù)讀寫。最后利用TI公司提供的DSP專用開(kāi)發(fā)工具CCS2.2，完成DSP的內(nèi)部程序編寫與在線調(diào)試，使控制器可通過(guò)以太網(wǎng)使用ICMP或UDP協(xié)議與其他設(shè)備相連。 最終完成的多缸液壓機(jī)伺服控制器具有：8路數(shù)字量輸入輸出；8路模擬量輸入；8路模擬量輸出；8路SSI絕對(duì)式編碼器接口；1路以太網(wǎng)通訊接口。

The high-speed digital signal processor -DSP is used as the central processing chip of the controller. FPGA is used as the data preprocessing unit of the controller to complete the information exchange and preprocessing between DSP and external modules. To make all the logic of reading and writing by hardware, especially the speed measurement module in the FPGA as the form of hardware, In order to make the servo controller exchange information with other devices, the Ethernet communication interface is added. So that the controller can open access to the network and the upper computer for network communication.
