【摘要】：為改善溫度波動(dòng)對(duì)光通信用半導(dǎo)體激光器性能的影響,設(shè)計(jì)了基于三維語(yǔ)言變量的高精度跟蹤誤差溫度控制系統(tǒng)。為減小系統(tǒng)成本,利用運(yùn)算放大器AD620和OP07等器件設(shè)計(jì)了溫度采集系統(tǒng),并采用最小二乘法擬合溫度數(shù)據(jù),從而建立溫度—電阻關(guān)系模型,預(yù)測(cè)溫度變化趨勢(shì);加入第三維模糊語(yǔ)言變量,結(jié)合窄域論以適當(dāng)壓縮E、EC、ECC的論域,采用模糊規(guī)則設(shè)定方法,建立新型三維模糊PID規(guī)則表并求解得出模糊查詢表。結(jié)果表明:當(dāng)預(yù)設(shè)溫度為25℃時(shí),溫控系統(tǒng)超調(diào)量為0.97℃,最大下沖量出現(xiàn)在第17s,其值為0.69℃;工作51s后,LD系統(tǒng)進(jìn)入穩(wěn)定狀態(tài),溫度保持為25±0.05℃;在第150~210s內(nèi),其溫度值標(biāo)準(zhǔn)差為0.020 4℃。同時(shí),該系統(tǒng)實(shí)現(xiàn)了對(duì)半導(dǎo)體激光器0~75℃的大范圍精密溫控,溫控精度為±0.05℃。該系統(tǒng)能夠?qū)崿F(xiàn)對(duì)半導(dǎo)體的高效制冷、加熱控制,具有響應(yīng)時(shí)間快和系統(tǒng)開銷小的優(yōu)勢(shì),能對(duì)控制參數(shù)實(shí)現(xiàn)自整定。
[Abstract]:In order to improve the effect of temperature fluctuation on the performance of semiconductor lasers for optical communication, a high precision tracking error temperature control system based on 3D language variables is designed. The temperature acquisition system is designed by using operational amplifier AD620 and OP07, and the temperature data are fitted by the least square method, thus the temperature-resistance relation model is established, the trend of temperature change is predicted, and the third dimension fuzzy language variable is added. Combined with the narrow domain theory, a new three-dimensional fuzzy PID rule table is established by using the fuzzy rule setting method. The results show that the overshoot of the temperature control system is 0.97 鈩，
