    The Neoliberal State and Risk Society: The Chinese State and the Middle Class.Hai Ren - 2010 - Telos: Critical Theory of the Contemporary 2010 (151):105-128.
    How do we theorize the Chinese state, a state both transforming itself rapidly through economic rationalism and yet standing firmly through governmental authoritarianism? Where and how is the figure of the middle class situated in this Chinese state? How does a critical understanding of the Chinese situation offer insights into problems of risks associated with the middle class in the current global economic crisis/recession? To address these questions, I look at both the politics of the Chinese state and its transformative (...)

    Boost Converters’ Proximate Constrained Time-Optimal Sliding Mode Control Based on Hybrid Switching Model.Asghar Taheri, Amir Ghasemian & Hai-Peng Ren - 2019 - Complexity 2019:1-14.
    It is well known in the literature studies that the theoretical time-optimal control of boost converters can be achieved using switching surfaces based on the converter’s natural state trajectories. However, this method has two important drawbacks: First, the transient current peak of the time-optimal controller is far beyond the current limitations of related circuit elements in many practical cases. Second, switching based on the converter’s natural trajectories has high computational complexity and high dependence on circuit parameters. In this paper, based (...)

    Sensorless Direct Torque Control of the Six-Phase Induction Motor by Fast Reduced Order Extended Kalman Filter.Asghar Taheri, Hai-Peng Ren & Chun-Huan Song - 2020 - Complexity 2020:1-10.
    In this paper, a simple extended Kalman Filter controller for direct torque control of a six-phase induction machine in all speed ranges is proposed. The aim of this paper is to decrease the execution time of EKF modeling of a six-phase induction motor. The proposed method is fast and can operate online. If the machine parameters are changed during the operation, the EKF algorithm is activated to find parameters used for controlling the motor. In low speed, not only the motor (...)
