摘 要
洗凈率作為工業(yè)洗滌機(jī)的一項(xiàng)重要技術(shù)指標(biāo)，其優(yōu)劣直接影響到洗滌的質(zhì)量和效率，本文通過(guò)對(duì)江蘇海獅機(jī)械集團(tuán)與江蘇科技大學(xué)產(chǎn)學(xué)研合作項(xiàng)目洗滌龍的國(guó)內(nèi)外發(fā)展現(xiàn)狀及洗滌工藝的研究分析，確定了影響洗滌龍洗凈率關(guān)鍵因素為洗滌溫度和洗滌轉(zhuǎn)動(dòng)角度。
洗滌溫度是影響洗凈率的關(guān)鍵因素之一，因其本身具有大慣性、非線性、大時(shí)滯等特點(diǎn)，在對(duì)溫度控制策略研究后，采用模糊PID算法和預(yù)估補(bǔ)償算法相結(jié)合的方法實(shí)現(xiàn)控制，通過(guò)仿真分析表明所設(shè)計(jì)的預(yù)估模糊PID控制器較常規(guī)PID控制器具有超調(diào)小、響應(yīng)快、魯棒性強(qiáng)的優(yōu)點(diǎn)，表現(xiàn)出了良好的動(dòng)、穩(wěn)態(tài)性能。
洗滌龍監(jiān)控系統(tǒng)由硬件和軟件組成，硬件設(shè)計(jì)采用IPC+現(xiàn)場(chǎng)總線+PLC分布式控制的設(shè)計(jì)方案，確定了系統(tǒng)主要配置，給出了洗滌推進(jìn)角度控制和洗滌溫度控制的硬件電路原理圖?？刂葡到y(tǒng)的軟件設(shè)計(jì)分為下位機(jī)PLC控制程序設(shè)計(jì)和上位機(jī)監(jiān)控軟件設(shè)計(jì)，分別采用XCPPro V3.1程序軟件和組態(tài)王6.53組態(tài)軟件來(lái)實(shí)現(xiàn)。下位機(jī)PLC程序設(shè)計(jì)中實(shí)現(xiàn)了預(yù)估模糊PID控制算法和洗滌轉(zhuǎn)動(dòng)角度的閉環(huán)控制。上位機(jī)監(jiān)控軟件由多個(gè)界面構(gòu)成，能實(shí)時(shí)地監(jiān)控洗滌龍系統(tǒng)的運(yùn)行狀態(tài)，并能方便的設(shè)定各項(xiàng)參數(shù)。
洗滌龍經(jīng)過(guò)現(xiàn)場(chǎng)調(diào)試和洗凈率檢測(cè)實(shí)驗(yàn)后，表明該控制方法可以有效地提高系統(tǒng)自動(dòng)化程度和洗凈率控制精度，獲得了預(yù)期控制效果，為日后的研究提供了參考依據(jù)。

Abstract
Clear rate is one of the most important indexes of industrial washing machines; it can directly affect the quality and efficiency of the industrial washing machine. By means of doing research and analysis of developing situation of domestic and foreign and washing technology of the joint research cooperation project Continuous batch washer of Jiangsu sea-lion machinery group and Jiangsu university of science and technology，the paper determines that the key factors of clear rate are temperature and washing rotary angle.
Since the factor of temperature has large inertia, nonlinear, big delay characteristics, in the control strategy research we use fuzzy PID algorithm and estimate method combining compensation algorithm to realize control, then the results by simulation research indicate that the fuzzy-PID controller with predictive model designed has better features of overshoot small，fast response ,strong robustness than conventional PID controller, and also showed a good dynamic and static performance.
Continuous batch washer’s intelligent monitoring system is composed by both hardware and software. Hardware system is a distributed control system composed by IPC, CAN and PLC. The paper points out the main function and selection of major dispositions and circuit principle diagram of washing rotation angle control and temperature control. The control system software is designed into two parts which are the PLC control programs and PC monitor software, by using XCPPro V3.1 program designing software and KingView 6.53 configuration software separately. The PLC control programs can realize closed-loop control of fuzzy-PID controller with predictive model designed and washing rotary angle. The IPC monitor software consists of multi-interfaces. It can monitor the operating states of continuous batch washer system in real time, and set every parameter conveniently.
After on-line debug and clear rate test, we prove that the control method we designed in this paper can effectively improve the autoimmunization and control precision of clear rate. The design gets the expected control effect and provides reference basis for future research.
