摘　　要：针对实验室A3000液位控制系统使用工控机控制成本较高,且PID控制器效果不甚理想,设计了基于嵌入式智能仪表的DMC先进控制器。动态矩阵控制(DMC)采用阶跃响应序列作为对象模型,它具有模型获取简便、算法易实现、鲁棒性强的特点,在工业过程中得到了广泛应用。该控制器以ARM9微处理器S3C2410A为硬件平台,扩展模拟量输入输出和网络接口,基于ARMLinux操作系统,将DMC算法在嵌入式智能仪表上实现。在局域网内,通过Web服务、网络客户端配置控制器参数。在A3000上实验结果表明,与经典PID控制器相比较,该控制器具有良好的控制效果,这对于工业过程控制具有重要的工程意义。The DMC controller is designed based on the embedded intelligent instrument,considering the big price of the industrial personal computer and PID controller's bad performance on the A3000 liquid level system.The dynamic matrix control algorithm is based on the unit step response sequence.It is widely used in industrial processes because of its multitudinous virtues.DMC algorithm is realized in the ARM9 processor hardware platform named S3C2410A with AD/DA and network interfaces,based on ARMLinux OS. In LAN,the controller parameters can be configured by the web server and PC client.It is applied on the the A3000 liquid level system, compared with the classic PID controller,the satisfactory control performance is obtained.
