本文通过数字仿真手段,研究了计算机控制中PID、DB、DAHLIN和FTSC算法。文中以一典型的含时延二阶被控对象为例,给出了主要的仿真结果,分析、比较了这些算法在动态品质、控制变量幅度和对对象参数变化的敏感程度等方面的优劣。并讨论了这些算法的时间复杂度,采样周期等问题。
In this paper, numerical simulation methods are used to study PID, DB, DAHLIN and FTSC algorithms in computer control. Taking a typical second-order controlled object with time delay as an example, the main simulation results are given, and the advantages and disadvantages of these algorithms in terms of dynamic quality, control variable magnitude and sensitivity to changes in object parameters are analyzed and compared. . And discussed the time complexity of these algorithms, sampling period and other issues.
