【摘要】：組合積分系統(tǒng)多采用傳統(tǒng)方法進行控制，如PID控制、Smith預(yù)估控制、內(nèi)�？刂�、模糊PID控制及抗時滯偽PI控制，，都取得不錯控制效果。雖然組合積分系統(tǒng)已在工業(yè)控制領(lǐng)域中廣泛存在，但至今尚未引起廣大工程技術(shù)人員關(guān)注，多數(shù)研究者們將關(guān)注點放在組合積分系統(tǒng)控制策略方面，其它應(yīng)用研究較少。本文分析組合積分環(huán)節(jié)低通濾波實質(zhì)，通過組合積分環(huán)節(jié)設(shè)計低通、高通、帶通濾波器。將組合積分濾波環(huán)節(jié)與預(yù)測PI控制算法應(yīng)用到煙草含水率控制系統(tǒng)中，更好的實現(xiàn)對控制系統(tǒng)穩(wěn)定性分析。從理論研究到工程實踐，可分為以下兩個部分： （1）低通、高通、帶通濾波器設(shè)計 基于組合積分環(huán)節(jié)低通濾波原理，提出采用組合積分環(huán)節(jié)與延時環(huán)節(jié)設(shè)計低通、高通、帶通濾波器的方法。確定濾波器參數(shù)選擇原則，并分析其相對于數(shù)字濾波器優(yōu)點。 （2）組合積分環(huán)節(jié)與預(yù)測PI控制算法結(jié)合應(yīng)用 煙草工藝過程中常存在周期性干擾，烘絲出口含水率僅能控制在±5%范圍內(nèi)。將組合積分環(huán)節(jié)與預(yù)測PI控制算法結(jié)合在烘絲含水率控制過程中的應(yīng)用表明：可以使出口含水率保證在±0.3%范圍內(nèi)，保證出口含水率的穩(wěn)定。對比控制系統(tǒng)前后超調(diào)量，突出該策略對控制系統(tǒng)穩(wěn)定性分析的優(yōu)勢。 采用LabWindows/CVI作為軟件開發(fā)平臺，開發(fā)通用的組合積分系統(tǒng)先進控制軟件。Simulink搭建組合積分系統(tǒng)過程控制模型，先進控制算法通過DDE通訊技術(shù)進行數(shù)據(jù)交換。該方法在不影響工業(yè)生產(chǎn)的同時，又能夠有效的對軟件的各項功能進行測試。
[Abstract]:The combined integral system is controlled by traditional methods, such as PID control Smith predictive control, internal model control, fuzzy PID control and anti-delay pseudo-Pi control. Although the combined integral system has been widely existed in the field of industrial control, it has not yet attracted the attention of the vast number of engineers and technicians. Most researchers focus on the control strategy of combinatorial integral system, but few other applications. This paper analyzes the essence of low-pass filtering in combinatorial integration, and designs low-pass and high-pass through combinatorial integration. Band-pass filter. The combined integral filter and predictive Pi control algorithm are applied to the tobacco moisture control system, and the stability of the control system is better analyzed, from theoretical research to engineering practice. It can be divided into two parts: Low pass, high pass, band pass filter design Based on the principle of low pass filter in combinatorial integral link, a method of designing low pass, high pass and band pass filter with combination integral link and delay link is put forward, and the selection principle of filter parameters is determined. The advantages of digital filter are analyzed. Application of combination integral link and predictive Pi control algorithm Periodic interference often exists in the process of tobacco processing. The moisture content at the outlet of dried silk can only be controlled in the range of 鹵5%. The application of combination integral link and predictive Pi control algorithm in the control process of moisture content of dried silk shows that:. The moisture content of the outlet can be guaranteed in the range of 鹵0.3%. The stability of water content at the outlet is guaranteed, and the advantages of the strategy in analyzing the stability of the control system are highlighted by comparing the overshoot of the control system before and after the control system. Using LabWindows/CVI as the software development platform, the general advanced control software. Simulink is developed to build the process control model of the integrated integration system. The advanced control algorithm uses DDE communication technology to exchange data, which can effectively test the functions of the software without affecting the industrial production.
