Advanced Control for Quadruple Tank Process

“…1, March 2024, pp. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] Advanced Control for Quadruple Tank Process (Iput Kasiyanto)…”

“…This section will discuss a decentralized PID controller design for a multivariable system, studied by many researchers, see [9], [10], [13]- [21] for instance. But, before delving into PID control design, a brief overview of the relative gain array (RGA) will be described and analyzed.…”

“…The QTP can be considered as a prototype of many industrial applications in the process industry involving liquid level control such as chemical and petrochemical plants [12]. Previous research has explored various control strategies for the QTP, including decentralized PI/PID controllers [9], [10], [13]- [21], fractional order PI control [22]- [25], Model Reference Adaptive Controller (MRAC) [13], [26], state error feedback linearization control method with disturbance observer (DOB) and gain [27]- [30], low-gain integral controllers [31], generalized predictive control (GPC) [32], and sliding mode control [12], [23], [33]- [37], optimal control [38]- [40], and intelligent control techniques [21], [39], [41]- [49].…”

“…Furthermore, for a more obvious understanding, this study also compares the performance of the MPC with a decentralized PID control. Distinguishing itself from prior works that employed conventional controllers [9], [10], [14], or multiple MPCs [8], our approach deploys a single MPC.…”

Learning Enhancement of Control Engineering: A Competition-Based Case

“…In addition, students perceive a gap between theory and practice [31], which makes it difficult to understand and assimilate concepts [32]- [34]. To VOLUME 10, 2022 overcome these drawbacks, the trend has been to use testbed platforms representing real laboratory-scale processes on which to develop practices to improve the acquisition of knowledge and skills [35]- [41]. The current proposal extends this philosophy by adding a competitive component, giving rise to a national competition under the umbrella of the Spanish Committee of Automatics (CEA) [42], [43], to asses whether this new approach improves the learning process.…”
