标准的ADRC控制器通常以级联积分器的形式选择典型对象。然而,实际系统的条件变量并不一定具有级联积分关系。为此,本文提出了一种多元复合函数全导数的方法和一种将非级联积分形式的状态空间系统转化为级联积分形式的结构。这样,转换后的系统可以直接用ADRC控制。同时,对Chen混沌系统的控制进行了详细的讨论,给出了系统的转换和控制器的设计。研究了在不同复杂程度和不同干扰强度下的控制性能。转换后的系统在自抗扰控制器下的控制效果明显优于PID。这种转换方法从理论和应用上解决了某些非级联积分系统的控制问题,大大扩展了标准ADRC方法的应用范围。
The standard ADRC controller usually selects the canonical plant in the form of cascaded integrators. However, the condition variables of practical system do not necessarily have the cascaded integral relationship. Therefore, this paper proposes a method of total derivative of composite functions of several variables and a structure, which can convert the state space system of noncascaded integral form into the cascaded integral form. In this way, the converted system can be directly controlled with ADRC. Meanwhile, the control of Chen chaotic system is discussed in detail to show the conversion and the controller design. The control performances under different levels of complication and different strengths of disturbance are comparably researched. The converted system achieves significantly better control effects under ADRC than that of the PID. This converting method solves the control problem of some noncascaded integral systems in both theory and application and greatly expands the application scope of the standard ADRC method.
