“…Thus, there is a trade-off between gain and stability in the design of the ADRC. Previous implementation results [22] demonstrated that the tracking performance was imperfect for the FTS application to higher precision noncircular machining; reduced tracking error is needed. Hence, an error compensation controller [17] is added in the feed-forward loop of the ADRC to improve tracking performance.…”

“…Therefore, the model in Eq. (2) is measured with a software-based dynamic signal analyzer, using a ''swept sine'' method that generates fixed amplitude sine waves of various frequencies [22]. Since the frequency response of a system frequently needs to be described by algebraic expression usually comprised of the ratio of two frequency-dependent polynomials, the LEVY method of evaluating polynomial coefficients is used to determine the nominal frequency response, which is based on the miniaturization of the weighted sum of squares of the errors between the absolute magnitudes of the actual function and polynomial ratio for various frequencies [23].…”

“…The convergence and stability of LADRC have been proved in time domain [13,14] and frequency domain [15] [16]. The validity has been verified in many applications [17][18][19][20][21]. Consequently, LADRC has theoretical completeness and practicability.…”

The lever-type electric erection system is a novel kind of erection system and the experimental platform in this paper operates with varying loads and low-resolution encoder. For high accuracy trajectory tracking, linear active disturbance rejection control (LADRC) is introduced. An approximate model, consisting of the servo system configured at velocity control mode and the lever-type erection mechanism, is built by means of system identification and curve fitting. Reduced-order LADRC based on the further simplified model is proposed to improve tracking accuracy and robustness. As comparisons, traditional LADRC and PID with high-gain tracking differentiator (HGTD) are designed. Simulation and experimental results indicate that reduced-order LADRC can realize higher trajectory tracking accuracy with low-resolution encoder and has better robustness to variation in erection loads, compared with traditional LADRC and PID with HGTD.

“…In recent years, some positive research results have been made on the application of ADRC technology in various fields [4][5][6][7][8][9][10][11][12][13][14]. Active disturbance rejection control (ADRC) is a new control algorithm based on the extended state observer and the thought of eliminating error with error proposed by the famous Chinese scholar Han J. Q. in the 1990s [15][16], which inherits the "durability" and non-dependence of the mathematical model of the PID controlled system.…”

The problems of large time delay, high inertia, and parameter uncertainty of the spraying and drying temperature control system in the automatic production line can easily lead to the instability of the system and the deterioration of anti-interference ability. Therefore, a control method based on the active disturbance rejection control (ADRC) is presented to improve the temperature control performance of the spraying and drying process in the production line. In this paper, a nonlinear ADRC temperature controller is designed, consisting of the tracking-differentiator (TD), the extended state observer (ESO), and the non-linear state error feedback (NLSEF). The ADRC controller does not rely on accurate spraying and drying process models, and it can solve the problem that the spraying and drying temperature is affected by various internal or external disturbance factors on the controlled system. Therefore, the temperature control performance of the system is improved. Simulation results show that compared with the traditional PID controller, the designed ADRC controller achieves high performance in dynamic performance, robustness, and disturbance rejection.
