Abstract EN
The Active Disturbance Rejection Control (ADRC) prefers the cascaded integral system for a convenient design or better control effect and takes it as a typical form.
However, the state variables of practical system do not necessarily have a cascaded integral relationship.
Therefore, this paper proposes an algebraic substitution method and its structure, which can convert a noncascaded integral system of PID control into a cascaded integral form.
The adjusting parameters of the ADRC controller are also demonstrated.
Meanwhile, a numerical example and the oscillation control of a flexible arm are demonstrated to show the conversion, controller design, and control effect.
The converted system is proved to be more suitable for a direct ADRC control.
In addition, for the numerical example, its control effect for the converted system is compared with a PID controller under different disturbances.
The result shows that the converted system can achieve a better control effect under the ADRC than that of a PID.
The theory is a guide before practice.
This converting method not only solves the ADRC control problem of some noncascaded integral systems in theory and simulation but also expands the application scope of the ADRC method.
