摘　　要：针对三容水箱系统大时滞、动态响应慢问题,研究了三容水箱系统的液位跟踪控制。采用模型预测控制策略,设计了三容水箱的液位跟踪控制器,并通过FPGA加以实现。控制器硬件和软件系统采用基于NiosⅡ嵌入式软核处理器的FPGA/SOPC方案,在基于FPGA和dSPACE的平台上,进行了实时联合仿真。实验结果表明,基于FPGA的模型预测控制器能够实现对三容水箱系统的液位跟踪控制。该实验可应用于自动控制、过程控制等相关课程教学,方便高效,具有较好的实验演示效果。In view of the problem about the large time delay and slow dynamic response of the three-tank system, the liquid level tracking control of the three-tank system is studied. By using the model predictive control strategy, the liquid level tracking controller of the three-tank water tank is designed and implemented by FPGA(field programmable gate array). FPGA/SOPC(system on programmable chip) scheme based on Nios Ⅱ embedded soft core processor is adopted for the hardware and software system of the controller. The real-time joint simulation is carried out on the platform based on FPGA and dSPACE. The simulation results show that the model predictive control based on FPGA can drive the three-tank system to track a predefined liquid level. This experiment is convenient and efficient in the teaching of relevant courses of automatic control and process control, which has good experimental demonstration effect.
