摘　　要：通过对电网配电与负荷控制模型的波动过程进行分析,模拟控制过程反馈状态特点,结合电网负荷结构模型的变量引入MAC(模型反馈算法控制)改进输出稳定的多域值延迟问题,与传统的PID控制比较得出,在积分变量或输入信号变化时,只要根据九点-逻辑控制策略进行调整,就可以得出较为理想的控制与输出结果。通过建立SimuLink仿真模型并通过Matlab.m程序表明,其控制结果在模型匹配时性能良好,在模型失配时依然能满意运行,使波动幅度和误差精度都达到要求。Through an analysis of control process for concrete batching mixing plant dynamic ingredient system,Simulating characteristics of human intelligent,combined with the variables of the power grid load structure model,MAC is introduced to improve the multi domain delay problem of output stabili-ty,compared with traditional PID control,it is concluded that,when the integral variable or input sig-nal changes,just adjust according to the nine point logic control strategy,we can get ideal control and output results.Simulated results based on MATLAB prove that this controller has simple structure,clearly physics background and mathematical concepts.Its shows good performance when predictive model matches and satisfactory results when model mismatch,the precision and rate of system batch-ing all fulfill the requirement,the efficiency of system is also improved.
