Composite Autonomous Anti-disturbance Control for Systems with Multiple Disturbances

Complex systems in various fields including robot, aerospace, advanced manufacturing, and others are affected by heterogeneous disturbances and uncertainties resulting from internal disturbances, external disturbances, and model errors. With the increasing of requirements for accuracy, stability, and reliability, enhancing the ability of autonomous anti-disturbance control in complex environment has become the theoretical bottleneck and engineering challenge in the field of automation and artificial intelligence. This paper firstly reviews the traditional control methods that can attenuate or compensate a single kind of disturbance or an “equivalent” disturbance. Then, the paper introduces the theory of “refined” quantification and analysis under the influence of multiple disturbances and uncertainties, and subsequently proposes a composite anti-disturbance control law with hierarchical architecture: Composite Hierarchical Anti-Disturbance Control (CHADC). CHADC includes the disturbance description, disturbance estimation, disturbance compensation in feedforward path and the controller with disturbance attenuation in feedback path. The observability, compensability and repressibility of disturbances are proposed for the external observability and controllability of systems with disturbances. For the attitude control system of spacecraft, the experiment and simulation equipments of whole-loop anti-disturbance control are developed, which includes attitude estimation, controller, and execution parts. This technology can accomplish the whole-loop quantification and analysis of heterogeneous disturbances, as well as simultaneous attenuation and rejection of the heterogeneous disturbances. Consequently, the autonomous anti-disturbance performances of systems can be improved significantly.

Evolution Towards Quantum Metrology and the Action Agenda for Developing IT-Enabled Metrology

Quantum metrology and informatization of metrology are two major directions for metrology innovation. A new generation of information technologies, represented by the Internet, big data and artificial intelligence, are booming and has brought a far-reaching impact on scientific research around the world. In 2018, the General Conference on Weights and Measures (CGPM) at its 26th meeting adopted a Resolution on the revision of the International System of Units (SI) to redefine all SI base units in terms of physical constants. This revision terminated the history of using artefacts as measurement standards, and ushered in a new era of “modern metrology” where measurements are largely based on quantum technologies. China has played a vigorous part in the global research cooperation enabling the SI revision. Furthermore, China has proposed to establish a quantum-based national advanced measurement system where quantum measurement standards and a “flattened” traceability chain will be the core features. This action will help incorporate quantum metrology into informatization programmes of China, accelerating the integration between quantum technology and information technology.

Implementation of the Informatization Application Scenario for Prevention and Control of Desertification in the China-Mongolia-Russia Economic Corridor of the Belt and Road Initiative—Taking the China-Mongolia Railway (Mongolia Section) as an Example

The areas of the China-Mongolia-Russia economic corridor in the Belt and Road Initiative are characterized by a complex natural geography, a fragile ecological environment, and serious desertification. Its impact on the main traffic trunk lines between China, Mongolia, and Russia is not clear, which brings risks and challenges to infrastructure construction. The completion of dynamic monitoring and risk assessment of desertification in areas along the China-Mongolia-Russia economic corridor is urgently required. Faced with the above problems, this study, based on research information and GIS technology, carried out a desertification remote sensing inversion algorithm, a big data application platform, and multi-source data fusion and integration, and established application scenarios for desertification risk control. In this application, based on the extraction effect comparison of different characteristic space models, a desertification information extraction model algorithm suitable for the China-Mongolia-Russia economic corridor is constructed. Using modes of big data batch processing and real-time processing, the desertification information along the corridor was extracted, analyzed, and dynamically monitored. Combined with historical data, the diagnosis and testing of desertification patterns and changes within 200 km of both sides of the China-Mongolia Railway (Mongolian section) from 1990 to 2015 have been completed. This application scenario is oriented to multi-source, multi-scale, and long-time series earth observation satellite data. Based on the big data batch processing technology driven by cloud computing, it realizes high-throughput processing, rapid analysis, and the visual display of long-time series desertification dynamic information. It has the ability to monitor desertification dynamically and can provide information and decision-making support for the prevention and control of desertification in key areas of the China-Mongolia-Russia economic corridor.
