Conditional Randomization Tests for the Specification of Interference Structure

Journal of Applied Econometrics, EarlyView.
ABSTRACT This study proposes specification tests for interference structure in causal inference with spillovers. We focus on experimental settings in which the treatment assignment mechanism is known. To test whether a given exposure mapping adequately summarizes the true interference structure, we develop conditional randomization tests by utilizing ...

Comments on Active Disturbance Rejection Control

IEEE Transactions on Industrial Electronics, 2007
This paper presents comments on active disturbance rejection control (ADRC) in four aspects as follows: (1) tracking differentiator; (2) nonlinear combination of proportional, integral, and differential errors; (3) extended state observer; and (4) disturbance rejection. Applications of ADRC are briefly introduced.

Active disturbance rejection control: Old and new results

Annual Reviews in Control, 2017
Abstract The active disturbance rejection control (ADRC), first proposed by Jingqing Han in the 1980s is an unconventional design strategy. It has been acknowledged to be an effective control strategy in the absence of proper models and in the presence of model uncertainty.

Active disturbance rejection control for fractional-order system

ISA Transactions, 2013
Fractional-order proportional-integral (PI) and proportional-integral-derivative (PID) controllers are the most commonly used controllers in fractional-order systems. However, this paper proposes a simple integer-order control scheme for fractional-order system based on active disturbance rejection method. By treating the fractional-order dynamics as a
