  • Tendon-Driven Variable Impedance Control Using Reinforcement Learning

    Biological motor control is capable of learning complex movements containing contact transitions and unknown force requirements while adapting the impedance of the system. In this work, we seek to achieve robotic mimicry of this compliance, employing stiffness only when it is necessary for task completion. We use path integral reinforcement learning which has been successfully applied on torque-driven systems to learn episodic tasks without using explicit models. Applying this method to tendon-driven systems is challenging because of the increase in dimensionality, the intrinsic nonlinearities of such systems, and the increased effect of external dynamics on the lighter tendon-driven end effectors. We demonstrate the simultaneous learning of feedback gains and desired tendon trajectories in a dynamically complex sliding-switch task with a tendon-driven robotic hand. The learned controls look noisy but nonetheless result in smooth and expert task performance. We show discovery of dynamic strategies not explored in a demonstration, and that the learned strategy is useful for understanding difficult-to-model plant characteristics.

  • Control and Protection of MMC¿¿?HVDC under AC and DC Network Fault Contingencies

    The modular multilevel converter (MMC) has become the most attractive voltage source converter (VSC) topology for high¿¿?power applications. AC or dc short¿¿?circuit fault conditions cannot be avoided in high¿¿?voltage direct current (HVDC) schemes, independent of the converter and the transmission link technology (e.g. cables or overhead lines). The probability, frequency, and characteristics of these faults depend on the employed transmission technology, converter technology (e.g. two¿¿?level or MMC), and the grounding topology (e.g. direct, resistive, or high¿¿?impedance). This chapter presents and compares the two¿¿?level VSC¿¿?HVDC and MMC¿¿?HVDC fault characteristics and behaviors under ac and dc fault conditions. It discusses the impacts of different component failures, and presents related control and protection techniques. VSC¿¿?HVDC terminals are designed to fulfill FRT requirements and remain synchronously connected to the network and provide the required ancillary services during the unbalanced ac fault conditions. Different techniques are applied to detect and protect the converter components from ac and dc fault conditions.

  • SelfImpedance and Mutual Impedance, Feeding Structures

    First published in 1981, Robert S. Elliott's Antenna Theory and Design is one of the most significant works in electromagnetic theory and applications. In its broad-ranging, analytic treatment, replete with supporting experimental evidence, Antenna Theory and Design conveys fundamental methods of analysis that can be used to predict the electromagnetic behavior of nearly everything that radiates. After more than two decades, it remains a key resource for students, professors, researchers, and engineers who require a comprehensive, in-depth treatment of the subject. In response to requests from many of our members, IEEE is now reissuing this classic. Newly revised, it once again will be an invaluable textbook and an enduring reference for practicing engineers. The IEEE Press Series on Electromagnetic Wave Theory offers outstanding coverage of the field. It consists of new titles of contemporary interest as well as reissues and revisions of recognized classics by established authors and researchers. The series emphasizes works of long-term archival significance in electromagnetic waves and applications. Designed specifically for graduate students, researchers, and practicing engineers, the series provides affordable volumes that explore and explain electromagnetic waves beyond the undergraduate level.

  • Power System Control and Estimation in a Competitive Environment

    Electric power grids are machines that span continents, with dynamics that are correspondingly complex. Further complications to the operation of power networks have now arisen in many parts of the world as a consequence of the deregulation and competition underway in the industry. Vertical integration, centralized control, and conservative operation in the past helped ensure stability and reliability in power supply. In a competitive, deregulated environment, in which none of these strategies is feasible, assuring reliability is considerably more difficult. The synchronous ac power grid is a unique entity in that the rotating generators connected to the grid are all dynamically coupled, regardless of geographical or topological separation. Imbalance of generation and consumption has instaneous ripple effects on all generators and loads. In the past, with conservative approaches to power plant operation, power grid loading, and the overall network control, power system behavior was sufficiently well behaved that linear control design proved reasonably effective. Today, nonlinear, decentralized control and optimization techniques are needed. Several new technologies are being explored in this context. High-sampling rate sensors and time synchronization via the global positioning system (GPS) may permit state estimations of greater accuracy. Flexible ac transmission devices (FACTS), especially within the so-called universal power flow controllers, promise substantially greater control over the transmission systems, permitting network operators to route power independently of network impedance characteristics. New algorithmic technologies are also under active investigation, including agent-based modeling and optimization and randomized algorithms.

  • Modeling of System Components for Harmonic Analysis

    Harmonic power flow analysis requires that the system components are adequately modeled with respect to frequency. Commercially available softwares have varying capabilities. This chapter provides the fundamental basis of modeling of major system components that include transmission lines, cables, filter reactors, transformers, induction motors, synchronous generators, and converters. Cables have higher capacitance than overhead lines; therefore, modeling of cable capacitances is of much significance for harmonic analysis. The zero sequence impedance of the lines and cables is dependent on the current flow through a conductor and return through the ground, or sheaths, and encounters the impedance of these paths. The system impedance to harmonics is not a constant number. The fundamental frequency impedance is inductive, its value representing the stiffness of the system. Three-phase models of transformers with neutral grounding impedances, mutually coupled lines, distributed parameter transposed, and untransposed transmission lines should be possible in the harmonic analysis program.
