For micro-newton-scale thrust systems in drag-free satellite, cold gas thrust and field ionization thrust usually require fast and stable flow control. In order to achieve high precision, low noise and fast response thrust control, stable and continuous flow control is the premise. At present, piezoelectric proportional valve composed of piezoelectric actuator and needle valve is widely used in flow control. However, the nonlinear characteristics of piezoelectric proportional valve such as hysteresis and creep are the main factors of internal disturbance in flow control system. Therefore, an active disturbance rejection control algorithm based on the improved Bouc-Wen (B-W) model is proposed in this paper. Firstly, the theoretical model and the phenomenological B-W model are combined to establish the improved B-W model, and then the model is applied to the active disturbance rejection control (ADRC) algorithm with known modeling corrections. Finally, simulation experiments are carried out. The simulation results show that the proposed method can effectively compensate and suppress nonlinear disturbances such as hysteresis and creep of piezoelectric proportional valve, thus improving the accuracy of flow control. © 2023 Technical Committee on control Theory, Chinese Association of automation.

This paper deals with the sampled-data semi-global robust practical output voltage tracking problem for single-phase voltage source uninterruptible power supply inverters. We construct an aperiodic sampled-data state feedback control law in an internal model principle framework. Lyapunov analysis shows that as long as the upper bound of the sampling time interval of the controller is less than an explicitly computable threshold, our problem can be handled by the proposed sampled-data control law. And the tracking error is guaranteed to approach a given neighborhood of the origin asympotically. © 2023 Technical Committee on control Theory, Chinese Association of automation.

Aiming at the demand of distributed energy production management system for intelligent operation and maintenance, considering the problems in current log analysis method, we propose an intelligent log analysis technology for distributed energy production management system. This technology applies distributed log framework to achieve the collection, storage, analysis and display of various equipment and service logs in the energy production management system. On the one hand, we use log anomaly detection technology to realize the anomaly detection of single node and the generating of log anomaly alarm, On the other hand, we use rule reasoning technology to realize the analysis and tracing of log anomaly alarm. In addition, we combine with practical application, optimize the traditional rule matching algorithm, which improves the fault tolerance of the matching network, and gets better accuracy and efficiency of the algorithm. © 2023 IEEE.

The integrated control method, active disturbance rejection control (ADRC) combined with internal model control (IMC), is proposed for non-minimum phase systems. The ADRC combined with IMC is to reduce the influence of zeros on right half plant (RHP), system uncertainty and outer disturbance. An improved IMC is put in the inner loop and ADRC is adopted in the outer loop. In order to enhance the system's stability, an approximate zero phase error model of controlled plant (ZPEM) is used as the internal model in the IMC control loop where the feedback of the inner loop is the dynamic weighted filter sum of the real output and the ZPEM output. The theoretical analysis and simulations verify effectiveness of the proposed method for non-minimum phase systems. © 2023 Technical Committee on control Theory, Chinese Association of automation.

For the gimbal servo system, multiple disturbances restrict the improvement of its angular velocity tracking accuracy. Aiming at solving this problem, a harmonic disturbance observer-based composite controller is developed in this paper. Firstly, multiple disturbances are modeled, Fourier analyzed, and classified based on frequency distribution characteristics. Secondly, a robust control method is designed based on loop-shaping technology for the gimbal servo system to ensure servo performance and suppress low-frequency disturbances. To estimate and compensate the imbalance vibration, a harmonic disturbance observer (HDO) is proposed according to the frequency information of imbalance vibration. Finally, numerical simulations are carried out to evaluate the effectiveness of the proposed method. © 2022 IEEE.

Industrial alarm systems play crucial roles in assessing the production status and ensuring process safety. However, the presence of alarm floods can make alarm systems partially or fully fail, and thus would cause serious consequences. Alarm prediction, as an advanced approach to address alarm floods, offers operators decision supports when an alarm flood occurs. Existing alarm prediction methods requires that the output alarm sequences are of a fixed dimension, making such methods unable to adapt to the changing alarm rate. Accordingly, this paper proposes an alarm prediction model based on Transformer. The proposed model can predict alarm sequences with variational dimensions and can also achieve remarkable accuracy. The effectiveness of the proposed method is demonstrated by a case study with data from the Vinyl Acetate Monomer (VAM) simulation model. © 2024 Technical Committee on control Theory, Chinese Association of automation.

The aim of quantum metrology is to exploit quantum effects to improve the precision of parameter estimation beyond its classical limit. In this paper, we investigate the quantum parameter estimation problem with multiple channels. It is related but not limited to the following two important and practical quantum metrology problems:(i) Quantum enhanced metrology with control, whose aim is to improve the precision of quantum sensing by utilizing feedback or open-loop control;(ii) Practical quantum metrology where the underlying evolution of quantum probes may change from a unitary dynamics to an open system dynamics,owing to the inevitable decoherence during the quantum sensing operation. For various kinds of quantum multiple channels, the corresponding quantum channel Fisher information is derived. To demonstrate the results, some illustrative examples are given.
