| 英文摘要 |
| The stable control of suspension density is an important means to ensure the quality of dense medium separation fine coal. This paper focuses on the actual production of multi-rate sampling control of density loop, and proposes a
dense medium separation density control method based on multi-rate event-triggered control method. Firstly, lifting technology and a multi-rate identification method based on continuous learning is adopted to construct the multi-rate model of
density loop. Next, a model predictive controller based on event-triggered mechanism is designed, so that the density loop
can reduce the updating times of controller on the premise of ensuring control performance, so as to reduce the waste of
communication resources. The simulation results show the effectiveness of proposed control method. The study provides a
new method for the design of dense medium separation density controller in industrial internet framework. |
