摘　　要：本文通过对稳定土拌和站配料系统的控制过程进行分析,依据稳定土拌和站配料称重系统和定量控制相结合的思想,对配料称重过程中出现的误差和滞后现象进行分析,被控对象为在允许误差要求下的二阶系统和带延迟的二阶系统,对比PID控制的误差补偿方案,利用最小二乘算法对误差在线修正。Matlab仿真表明其算法对测量数据的误差修正效果良好。通过多次数据测试和仿真实验,其控制规律可以使系统运行比较稳定,避免配料精度大幅震荡,其配料精度和速度都达到要求,整个系统的效率也得到了提高。To analysis the control process of batching system of stabilized soil mixing station, based on the idea of combining dynamic weighing system on ingredients and quantitative control, making an analysis on the errors and lag phenomena appeared in the process of weigh ingredients, the controlled object for the permissible error in the request of second-order function and delayed second-order function, compared with the compensation program of PID control, using least-squares algorithm to correct errors on line.Matlab simulation shows that the effect of amendment is better. After multiple data testing and simulation experiments, the control law can make the system run more stable and avoid ingredients precision volatility, its ingredients meet the required precision and speed, the efficiency of the whole system has also been improved.
