This research focus on the position tracking control of the barrel pitching electro-hydraulic servo system with model uncertainties. Based on the established dynamic model of the sytem, a disturbance observer-based integral sliding mode control approach is proposed. The mismatched disturbance observer and the matched disturbance observer are respectively designed to estimate mismatched and matched disturbances. Then, the obtained estimates of the mismatched and matched disturbances are added into the integral sliding mode controller to further improve the control performance of the electro-hydraulic servo system. The stability and convergence of the proposed approach are proved in the sense of Lyapunov theory. Comparative experiments further verified the practical effectiveness of the proposed controller. © 2023 IEEE.

Multi-area automatic generation control of a renewable energy-based hybrid power systems using JAYA optimized model predictive control

This study uses JAYA optimized model predictive control to address a three-area load frequency regulation problem that actively involves stochastic renewable energy sources. Some physical constraints employed in the system model, such as the generation rate constraint, dead band, and time delay by governor-turbine, negatively impact the control performance of the classical MPC technique. As such, a more robust control scheme is required to get rid of this flaw. The JAYA algorithm is adopted to dynamically tune the parameters of MPC, which is a parameter-driven controller for optimal system performance. The performance indices such as the integral of square error (ISE), integral of time multiplied by square error (ITSE), integral of the absolute value of error (IAE), and integral of time multiplied by the absolute value of error (ITAE) have been used to compare the effectiveness of the proposed controller with the classical MPC with constant tuning parameters. The suggested controller is superior to the conventional MPC, as demonstrated by the results from the MATLAB/Simulink environment. (c) 2023 The Author(s). Published by Elsevier Ltd.

This paper presents the control Technique for a bi-directional AC-DC interlinking Converter and a fault protection scheme for an AC-DC Hybrid Microgrid. In this paper, an IEEE 7 bus ring main system-based AC-DC hybrid microgrid is modelled to validate the control techniques for the interlinking converter and bi-directional DC-DC BESS converter. The Proposed control technique helps to maintain a power balance in the system by facilitating power shearing between DC to AC or AC to DC subgrids depending on the load variation patterns of the two subgrids. In addition, AC Subgrid is subjected to different line-to-line and line-to-ground faults, which are further detected, classified and isolated by the developed protection scheme. This work aims to develop an adaptive protection scheme for different control modes of interlinking converters and present adequate protection against variable fault currents of the system. © 2023 IEEE.

The operation data of the predictive control system is nonlinear, sequential and dynamic. The implicit nonlinear transformation of the traditional support vector data description (SVDD) cannot represent the timing and dynamic characteristics of the operation data of the control system. To solve this problem, this paper proposes a predictive control performance degradation detection method based on weighted Deep-SVDD. First of all, the target optimization function of SVDD is redefined based on the architecture of deep neural network, and the Deep-SVDD monitoring model is constructed using the extracted deep features. Secondly, the concept of sliding windows is introduced in view of the difference in sensitivity of deep features to predicted performance degradation of control systems. Using dynamic data from the window to weight the impact of sensitive features to highlight system performance degradation and construct a weighted Deep-SVDD monitoring model. Finally, the algorithm implementation process is theoretically deduced. The effectiveness of the proposed method is verified by the simulation of Wood-Berry distillation tower predictive control system. © 2023 SPIE.

Multi-machine parallel operation of medium-voltage power generation vehicles can meet more load demand, which is an important development direction of mobile power generation vehicles. However, simple parallel connection mode will lead to abnormal working conditions. Therefore, it is necessary to consider the characteristics of parallel operation of medium-voltage power generation vehicles and put forward reasonable parallel operation control technology. In this paper, a multi-machine parallel operation control strategy for power generation vehicles is proposed to detect and adjust the voltage amplitude, frequency and phase of the units to be paralleled. The effectiveness of the proposed control strategy under various operating conditions is verified by a detailed parallel controller simulation model. © 2023 IEEE.

Due to the presence of nonlinear power devices in rectifiers, a large amount of harmonic pollution will be generated during system operation. Harmonic pollution has a significant impact on the stability and efficiency of the system, and may also lead to more serious *** response to the nonlinearity in the rectifier, this article adopts sliding mode control as the design method. During the research process, a mathematical model of the PWM rectifier system is first established, and then the control rate in the sliding mode controller is calculated based on the obtained mathematical model. The Fcn module in MATLAB is used to edit the formula based on the obtained system control rate to achieve sliding mode *** simulation verification, it can be seen that the rectifier control with sliding mode control has faster response speed, anti-interference ability, and robustness;When facing changes in a given voltage, sliding mode control quickly adjusts without static error. Therefore, the performance of sliding mode control is superior to that of PI control when controlling nonlinear systems. © 2023 IEEE.

control method of DC component for NNBI accelerator power supply

In the high voltage power supply of the negative ion source neutral beam injection system (NNBI) accelerator, the three-phase three-level neutral point clamping (NPC) inverter, as an inverter module, has a detectable DC component in its output. When it flows into the step-up transformer, it will lead to increased transformer loss and excitation saturation, thus reducing the service life of the transformer and increasing potential safety hazards. This paper analyzes the causes of the DC component of the NPC inverter, and a reliable DC component suppression method based on double-loop control is proposed. A suitable PI controller can effectively suppress the output DC component during the power supply operation by establishing the transfer function between the output DC component and the regulation rate of the switch's duty cycle. Finally, the prototype experiments verify the effectiveness of the control method successfully. (C) 2023 Published by Elsevier Ltd.

This research presents an eleven-level multilevel inverter with decreased switching count and voltage stress. There are only 7 switches in the architecture, including 1 bidirectional switch and 2 capacitors. The inverter circuit is given a gate pulse using a straightforward nearest level control (NLC), which is a fundamental switching frequency-based approach. To demonstrate the advantages of the presented topology, a comparison with recent topologies in terms of switches, diodes, sources, and capacitors employed in numbers is made. According to the IEEE 519-2014 standard, the total harmonic distortion (THD) is 8.6%, which is almost within acceptable bounds. Eventually, using the software PLECS and MATLAB (SIMULINK), the recommended architecture has been operationally and functionally simulated. Its experimental validation is also being done on the setup for various loading circumstances. © 2023 IEEE.
