    摘要:

    提出了一種基于VHDL語(yǔ)言描述、FPGA實(shí)現(xiàn)的聯(lián)合收獲機(jī)脫粒滾筒模糊控制系統(tǒng)的硬件設(shè)計(jì)方法。建立脫粒滾筒模糊推理規(guī)則和控制器算法結(jié)構(gòu)，完成了控制器的VHDL模塊化設(shè)計(jì)，并通過(guò)MAX+PLUSII開(kāi)發(fā)平臺(tái)，對(duì)各模塊進(jìn)行時(shí)序與功能仿真，實(shí)現(xiàn)了脫粒滾筒智能控制技術(shù)的單片集成。結(jié)果表明：用FPGA實(shí)現(xiàn)聯(lián)合收獲機(jī)脫粒滾筒模糊控制器，時(shí)序驗(yàn)證方便，而且推理速度快、修改靈活、系統(tǒng)集成度高，是實(shí)現(xiàn)智能控制策略的一種新的有效思路。

    Abstract:

    A design method of fuzzy control system of combine cylinder based on VHDL and FPGA was proposed. With the fuzzy logic toolbox of Matlab, the fuzzy inference rules and the algorithm architecture of cylinder were constructed. According to top-down mode, the VHDL modular design of the controller was carried out. Time simulation and function simulation of the fuzzy controller were proceeding on MAX+PLUSII, and the design was realized. The results indicate that FPGA implementation of fuzzy control about combine cylinder has many advantages, such as timing test is convenient, inference speed is high, design modification is agile, and system integration is great. It is an efficient method to implement intelligent control strategy. 
