本文探讨了多变量控制系统的扰动控制问题,分析了各种扰动控制原理的实现及其相应地必须满足的条件。最后以一实际的可控硅双闭环直流调速系统为例,对于突加负载,应用A通道扰动控制的理论,进行了输出不变的实验测试。给出了受扰系统在未加扰动控制和加了扰动控制这两种情况实拍的动态特性曲线,获得十分满意的效果。指出扰动控制在理论上和工程应用上重要的实际意义。
In this paper, the problem of disturbance control in multivariable control system is discussed. The realization of various disturbance control principles and the corresponding conditions must be satisfied. Finally, taking an actual silicon controlled double closed-loop DC speed governing system as an example, the experiment of constant output is carried out for the sudden load with the theory of A-channel disturbance control. The dynamic characteristics of the disturbed system in real motion with and without disturbance control are given, and the results are very satisfactory. Pointed out that the disturbance control in theory and engineering application of important practical significance.
