Improving habitability for wind-induced structural vibration by equivalent-input-disturbance approach

TL;DR: In this paper , the authors used a lagged-derivative function and an equivalent-input-disturbance (EID) approach to improve the habitability of a building for wind load.
Abstract: This paper improves the habitability of a building for wind load using an equivalent-input-disturbance (EID) approach. In these few decades, many high-rise buildings are constructed around the world. The influence of wind load is large for high-rise buildings, and it causes a decrease in habitability. Habitability relates to the acceleration of a structural response. To improve the habitability of a building for a wind load, we use a lagged-derivative function and EID approach. An EID approach estimates the effect of a disturbance on an output signal. Thus, an acceleration has to be output to estimate an EID. This paper uses a lagged derivative to output the acceleration. The numerical verification uses a building model of 240m and demonstrates that the presented method suppressed the absolute acceleration and improves the habitability of a building to a wind load.

TL;DR: Disturbance observer based control (DOBC) is regarded as one of the most promising approaches for disturbance attenuation as mentioned in this paper, due to its ability to compensate disturbances and uncertainties.
Abstract: Due to its abilities to compensate disturbances and uncertainties, disturbance observer based control (DOBC) is regarded as one of the most promising approaches for disturbance-attenuation. One of the first books on DOBC, Disturbance Observer Based Control: Methods and Applications presents novel theory results as well as best practices for applications in motion and process control that have already benefited numerous organizations.Supplying authoritative guidance in the areas of disturbance estimation and compensation for practical engineering systems, the book includes coverage of theoretic methods and practical applications of disturbance estimation and compensation for control systems through a DOBC approach. It considers applications in flight control systems, motion control systems, and process control systems. Supplies an authoritative overview of disturbance observer based control approaches Reports on recent developments in disturbance estimation techniques Considers matched and mismatched disturbance/uncertainty attenuation for DOBC Illustrates applications of the methods covered with detailed engineering case studies Filled with valuable insights gathered over decades of research by the authors, this book provides time- and stress-saving guidance for anyone interested in the theory and method research of DOBC. Using typical engineering examples, the text provides readers with an understanding of recent developments in DOBC as well as the tools required to make the most of this promising approach to disturbance-attenuation.

TL;DR: In this paper, a high-precision positioning control of a dual-stage feed drive was proposed based on the equivalent input-disturbance (EID) approach to improve the disturbance rejection performance.
Abstract: This paper deals with the high-precision positioning control of a dual-stage feed drive. The design of the control system is based on the equivalent input-disturbance (EID) approach to improve the disturbance rejection performance. An analysis of the EID approach reveals the mechanism of disturbance rejection. The design procedure is illustrated by a numerical example. Simulation results show that the EID control system not only rejects disturbances, but also suppresses uncertainties and nonlinearities in the plant. Design and simulation results for the example are also employed to compare our method with the disturbance observer method, and to demonstrate the validity of our method.

TL;DR: In this paper, an active mass damping (AMD) consisting of an AC servo motor, a movable mass connected to the servo motors by a ball-screw mechanism, and an accelerometer as a sensor for vibration measurement was considered.

TL;DR: The performance of active disturbance rejection control (ADRC) algorithms can be limited in practice by high-frequency measurement noise, so this problem is addressed by transforming the high-gain extended state observer (ESO) into a new cascade observer structure.
Abstract: The performance of active disturbance rejection control (ADRC) algorithms can be limited in practice by high-frequency measurement noise In this article, this problem is addressed by transforming the high-gain extended state observer (ESO), which is the inherent element of ADRC, into a new cascade observer structure Set of experiments, performed on a dc–dc buck power converter system, show that the new cascade ESO design, compared to the conventional approach, effectively suppresses the detrimental effect of sensor noise overamplification while increasing the estimation/control performance The proposed design is also analyzed with a low-pass filter at the converter output, which is a common technique for reducing measurement noise in industrial applications

TL;DR: In this paper, a new method of active structural control, which suppresses vibrations in civil structures due to seismic shocks, has been developed based on the equivalent-input-disturbance (EID) approach, which estimates the effect of a seismic shock and produces an equivalent control signal on the control input channel to compensate for it.
