Active Disturbance Rejection Control for Piezoelectric Smart Structures: A Review

Abstract

The piezoelectric smart structures, which can be labeled as the cream of the crop of smart structures without overstatement, are strongly impacted by a large number of uncertainties and disturbances during operation. The present paper reviews active disturbance rejection control (ADRC) technologies developed for application in piezoelectric smart structures, focusing on measurement, analysis, estimation, and attenuation of uncertainties/disturbances in systems. It first explained vast categories of uncertainties/disturbances with their adverse influences. Then, after a brief introduction to the application of basic ADRC in smart structures, a thorough review of recently modified forms of ADRC is analyzed and classified in terms of their improvement objectives and structural characteristics. The universal advantages of ADRC in dealing with uncertainties and its improvement on the particularity of smart structures show its broad application prospects. These improved ADRC methods are reviewed by classifying them as modified ADRC for specific problems, modified ADRC by nonlinear functions, composite control based on ADRC, and ADRC based on other models. In addition, the application of other types of active anti-disturbances technologies in smart structures is reviewed to expand horizons. The main features of this review paper are summarized as follows: 1) it can provide profound understanding and flexible approaches for researchers and practitioners in designing ADRC in the field and 2) light up future directions and unsolved problems.

Separation identification approach for the Hammerstein‐Wiener nonlinear systems with process noise using correlation analysis

“…Our future works will be performed from two aspects: first, the Hammerstein‐Wiener NFM‐FIR system with output noise is considered. In addition, the developed Hammerstein‐Wiener system can be used for practical system, for example, permanent magnet synchronous motor system control 52 and piezoelectric smart structures 53 …”

Bidirectional energy‐controlled piezoelectric shunt damping technology and its vibration attenuation performance

“…Equation ( 7) expresses the vibration displacement amplitude of the electromechanical model when the piezoelectric shunt damping circuit is always in the disconnected condition. Compared to this amplitude value, the vibration attenuation A (dB) controlled by the SSDI shunt damping circuit can then be calculated in Equation (15), in which the definition of the dimensionless parameter FOM (k m 2 Q m ) can be found in Equation (4).…”

“…The topic of how to suppress vibration has therefore attracted the attention of many scholars 1–3 . Among the vibration control techniques, the piezoelectric element‐based vibration control approach is very promising due to the direct electromechanical coupling effect, broadband operating frequency, and simple integration with structures 4,5 …”

Geometric Control and Structure-at-Infinity Control for Disturbance Rejection and Fault Compensation Regarding Buck Converter-Based LED Driver

“…Guaranteeing a stable system with fast responses using controllers is satisfactory and can ensure that the process has optimal and efficient production [9][10][11][12]. A variety of controllers have been applied to electrical systems and have focused on maintaining stable current or voltage, derived from the elements considered in the circuit, whose objective of the controllers is to follow the desired trajectories, taking into account the dynamic responses of the output variables [13][14][15]. In some research works, the decomposition into subsystems with fast or slow responses is necessary to design the controller and to be able to attenuate the disturbances in linear or non-linear systems [16][17][18].…”
