Three main findings were made: 1) With the increase of pressure, the viscosity of waxy oils with the same asphaltene content gradually increases, and the maximum increase can reach about 125 times at 10 °C. Compared with the waxy oils with low asphaltene content, the viscosity of waxy oils with high asphaltene content is more significantly affected by pressure. 2) Both pressure and asphaltene have influence on the yield value of waxy oil. With the increase of pressure, the yield value of waxy oil with the same asphaltene content decreases at first and then increases. When the pressure is the same, the yield value increases at first and then decreases with the increase of asphaltene content. 3) When the pressure is gradually increased, the storage modulus of waxy oils increases gradually, regardless of whether it contains asphaltene or not. On the contrary, the variation of loss modulus is not only related to pressure, but also to the system temperature.

However, external speed disturbances often occur during these operations. In response to this challenge, adjustments are made to the flow rate through the pig body, thereby modifying the pressure difference and achieving a targeted speed range of 1 to 3 m/s. Since a pig with an adjustable bypass port operates in a dynamically changing state, conventional control algorithms face difficulties in providing effective control. Moreover, there is limited research on speed control algorithms for pigs with adjustable bypass ports. To address these challenges, this paper introduces a control system based on quantitative feedback theory (QFT), coupled with cascaded proportional-integral-derivative (PID) tuning, for the precise speed control of a bypass pig. The state equation is derived from the pig’s operational state, and the QFT toolbox is employed to design a pre-filter and controller. This integration of QFT with cascaded PID not only facilitates both speed control and disturbance rejection but also demonstrates significantly improved control stability under variable operational conditions. The model, implemented using the Simulink toolbox, shows that this approach can quickly stabilize the pig’s speed, effectively managing continuous variations and enhancing the efficiency and safety of pipeline pigging.</div></div>","PeriodicalId":100824,"journal":{"name":"Journal of Pipeline Science and Engineering","volume":"5 2","pages":"Article 100231"},"PeriodicalIF":4.8,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144147048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
