“…This yields term n+m identically zero, thus making solution = 0 the only trivial equilibrium of the singularly perturbed observer error dynamics (35). Now, from (31), one can deduce that if ≡ẽ 0 is identically zero, then ẽ 0 =ẽ 1 = ⋯ =ẽ n−1 = 0 . Hence, expression z 1 =F = F becomes the perfect estimation of the total disturbance.…”

“…It is a case, for example, in some cascade-type control structures, teleoperation systems, missile guidance systems, formation control, rehabilitation manipulators, and power electronics devices, where the reference trajectory may result from a current action of an outer control system (e.g., cascade control) or from a current interaction with a different system (e.g., multi-subsystems plant). In the considered case of buck converter, an example can be a converter-fed DC motor system [31], in which the converter control forms the innerloop of a cascade connection with the motor and the control objective is defined at the outer-loop motor level (e.g., motor shaft position/velocity control).…”

In this work, the problem of designing a robust control algorithm for a DC-DC buck power converter is investigated. The applied solution is based on a recently proposed error-based version of the active disturbance rejection control (ADRC) scheme, in which the unknown higher-order terms of the reference signal are treated as additional components of the system "total disturbance". The motivation here is to provide a practical following of a reference voltage trajectory for the buck converter in specific cases where neither the analytical form of the desired signal nor its future values are known a'priori, hence cannot be directly used for control synthesis. In this work, the application of the error-based ADRC results in a practically appealing control technique, with compact structure, simplified control rule, and intuitive tuning (inherited from the conventional output-based ADRC scheme). Theoretical, numerical, and experimental results are shown to validate the efficacy of the error-based ADRC in buck converter control, followed by a discussion about the revealed theoretical and practical limitations of this approach.

“…The reasoning behind the specific selection of eADRC is that it is easily understandable by control practitioners since its structure allows immediate comparability with existing classical control solutions, including PI/PID, which are also error-based (in most instances). More detailed information about the eADRC can be found in [31,32,33,34] with some successful applications shown in [35,36,37,38].…”

In this paper, we uncover a new connection between standard PI/PID controllers and active disturbance rejection control (ADRC), from which we establish formal conditions of equivalence between the two control schemes. Using the equivalence, we devise a stepby-step procedure of transitioning from PI/PID to error-based ADRC. We also show how to go from 1DOF to 2DOF ADRC while retaining a standard 2DOF PI/PID structure. Both procedures facilitate expressing error-based ADRC schemes as standard industrial 1DOF and 2DOF controllers. This allows the designed controller to have the desired characteristic of ADRC (i.e. strong robustness against internal and external uncertainties) while still being expressed in a form that is familiar to industrial practitioners, where PI/PID structures are still the workhorse of modern control systems. The results of the paper ensure backward compatibility of future ADRC-based solutions and foster the adoption of active disturbance rejection-based methods in industrial practice as a viable alternative to standard controllers. To further support the findings, a set of tests is conducted in time and frequency domain, followed by a comparative analysis in FPGAin-the-loop simulation utilizing a realistic plant model.

In this paper, we uncover a new connection between standard proportional‐integral (PI), proportional‐integral‐derivative (PID) controllers and active disturbance rejection control (ADRC), from which we establish formal conditions of equivalence between the two control schemes. Using the equivalence, we devise a step‐by‐step procedure of transitioning from PI/PID to error‐based ADRC. We also show how to go from one degree‐of‐freedom (1DOF) to two degree‐of‐freedom (2DOF) ADRC while retaining a standard 2DOF PI/PID structure. Both procedures facilitate expressing error‐based ADRC schemes as standard industrial 1DOF and 2DOF controllers. This allows the designed controller to have the desired characteristic of ADRC (i.e., strong robustness against internal and external uncertainties) while still being expressed in a form that is familiar to industrial practitioners, where PI/PID structures are still the workhorse of modern control systems. The paper's results ensure backward compatibility of future ADRC‐based solutions and foster the adoption of active disturbance rejection‐based methods in industrial practice as a viable alternative to standard controllers. To further support the findings, a set of tests is conducted in time and frequency domain.
