摘要

针对自主研制的计算机控制三容水箱实验系统存在的数据采集精度低、可控性较差等问题

从硬件和软件两方面进行了优化设计。硬件上采用了ADuCM360芯片作为控制核心

设计采集控制板为4层电路板

并完成了相关功能的测试。软件上采用单位时间内各模块实时采样的方法

增加了采集的数据量。改变了阀门的控制策略

并进行了控制特性测试

通过MATLAB进行数据拟合

分析了阀门的可控程度。对优化后的系统采用了动态矩阵控制与比例—积分—微分(PID)控制结合(DMC-PID)串级控制算法进行仿真验证。结果表明:优化后的系统在稳定性与可控性方面均有提高。

Abstract

Aiming at the problems of low data collection accuracy and poor controllability for the self-developed computer control three-tank experimental system

the hardware and software are optimized.The ADuCM360 chip is used as the control core on the hardware.The acquisition and control circuit board is designed as a four-layer circuit board

and the functional test of the relevant circuit are completed.The software used the method for realtime sampling of each module in unit time

which increases the amount of data collected.The valve control strategy is changed and the control characteristics are tested.Through data fitting of MATLAB

the controllability of the valve is analyzed.DMC-PID（dynamic matrix control combined with PID control） cascade control algorithm is used to verify the optimized system.The results show that stability and controllability of the optimized system are improved.
